Product details
Overview
The MAX9202EUD+ from Maxim Integrated is a dual high-speed voltage comparator with TTL-compatible outputs and latch inputs, designed for precision timing-critical signal discrimination in mixed-signal systems. It delivers 7ns typical propagation delay (at 5mV overdrive), 9mW per comparator power consumption at +5V supply, and supports separate analog (±5V or +5V to +10V) and digital (+5V) supplies. It is used in high-speed A/D converters, line receivers, and PWM circuits where fast, low-power threshold detection with output hold capability is required.
For engineers reviewing the MAX9202EUD+ datasheet, MAX9202EUD+ pinout, MAX9202EUD+ application, or MAX9202EUD+ equivalent, this page provides verified functional specifications, validated dual-comparator timing behavior, confirmed TSSOP-14 package mapping, and real-world design context for signal restoration and sampling applications requiring latch-controlled output capture.
Technical Context
The MAX9202EUD+ integrates two independent comparators with internal TTL pullups and dedicated latch control inputs (LATCHA, LATCHB) that freeze output states on logic-low assertion. Its bipolar process enables rail-to-rail common-mode input range down to VEE (–5V), supporting ground-sensing operation with single +5V supply when VEE = GND.
Propagation delay is tightly matched between channels (∆tPD ≤ 2.5ns over temperature), and timing parameters-including tPD+(D) and tPD–(D) ≤ 10ns-guarantee deterministic latch-release response. Input offset voltage remains ≤ 7.5mV across –40°C to +85°C, ensuring stable threshold accuracy in industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 7ns typical (5mV overdrive); enables sub-10ns decision latency in high-speed sampling circuits. |
| Power per Comparator | 9mW at +5V supply; reduces thermal load and simplifies power budgeting in dense PCB layouts. |
| Analog Supply Range | +5V to +10V (VEE = GND) or ±5V; supports flexible system-level power architecture without level-shifting. |
| Input Common-Mode Range | VEE – 0.1V to VCC – 2.25V; allows direct sensing of signals referenced to negative rails or ground. |
| Output Drive Capability | VOH ≥ 3.0V @ 1mA sink, VOL ≤ 0.4V @ 8mA source; ensures robust TTL fan-out of four. |
| Latch Timing | tS = 2ns setup, tN = 1ns hold, tPW(D) = 8ns minimum pulse width; enables reliable capture in nanosecond-scale control windows. |
Pinout & Package
MAX9202EUD+ is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 4.4mm × 1.2mm), optimized for high-density mixed-signal PCBs with thermal and EMI performance advantages over SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN_– (A, B) | Negative input terminals for comparator channels A and B; accept differential or single-ended signals down to VEE. |
| 2, 9 | IN_+ (A, B) | Positive input terminals for channels A and B; support rail-to-rail common-mode range with <4pF input capacitance. |
| 3 | GND | Digital ground reference for VDD and latch inputs; must be isolated from analog ground (VEE) in split-supply configurations. |
| 4, 11 | LATCH_ (A, B) | TTL-compatible latch enable inputs; low-level assertion freezes respective comparator output state until next high-to-low transition. |
| 5, 12 | OUT_ (A, B) | TTL-output terminals with active internal pullups; drive standard LS-TTL loads without external resistors. |
| 6, 13 | N.C. | No internal connection; must remain unconnected and unbonded per Maxim design. |
| 7 | VEE | Negative analog supply and substrate bias; sets lower bound of input common-mode range and must be decoupled locally. |
| 10 | VDD | +5V digital supply for latch circuitry and output stage; requires dedicated 100nF ceramic decoupling capacitor. |
| 14 | VCC | Positive analog supply (4.75V–10.5V); powers comparator core and determines input dynamic range and speed. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel latch control | Independent LATCHA/LATCHB inputs allow asynchronous capture of two signal thresholds without shared timing constraints. |
| Rail-inclusive input range | Common-mode range extends to VEE – 0.1V, enabling direct interface with sensors or DACs operating near negative supply rails. |
| Matched channel timing | ∆tPD ≤ 2.5ns ensures synchronized decision latency between channels-critical for phase-sensitive applications like encoder decoding. |
| Low-power bipolar architecture | 9mW/comparator at +5V reflects optimized transistor count (176) and eliminates need for external bias networks or power sequencing. |
| TTL output integration | Internal pullups eliminate external resistors while maintaining full LS-TTL compatibility (fan-out of four) and reducing BOM count. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|
|
Use Scenario: Sampling analog input at >100 MSPS using flash or pipeline ADC architectures where comparator decisions define conversion windows. IC Role / Device Role / Timing Role: Dual comparator acts as front-end threshold detector and clock-synchronized sample gate, with latches capturing instantaneous analog levels prior to quantization. Use Value: 7ns propagation delay and 2ns setup time ensure minimal aperture jitter (<1ps RMS contribution), preserving effective resolution in 12-bit+ systems. |
Use Scenario: Receiving differential or single-ended data streams over twisted-pair or coaxial cables in industrial fieldbus or test equipment interfaces. IC Role / Device Role / Timing Role: Comparator functions as high-speed line receiver with hysteresis-free decision making; latch holds valid data during clock domain crossing or bus arbitration. Use Value: Rail-to-rail input range and TTL output drive directly interface with FPGA I/O banks or microcontroller GPIOs without level shifters or external buffers. |
| PWM Signal Conditioning | Threshold Detectors |
|
Use Scenario: Monitoring motor phase currents or switching node voltages in real-time to trigger fault shutdown or adaptive dead-time control. IC Role / Device Role / Timing Role: Dual comparator compares sensed current/voltage against programmable thresholds; latches capture peak or zero-crossing events for deterministic interrupt generation. Use Value: Matched channel delay (≤2.5ns skew) ensures simultaneous evaluation of complementary PWM edges, preventing false overcurrent triggers in three-phase inverters. |
Use Scenario: Detecting precise voltage thresholds in battery management, power supply supervision, or sensor alarm circuits. IC Role / Device Role / Timing Role: Comparator serves as ultra-fast window or level detector; latch holds alarm state until host MCU reads and clears condition. Use Value: 7.5mV max input offset and 250µV/V CMRR maintain threshold accuracy across temperature and supply variation-critical for <1% tolerance monitoring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator with latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9202EUD | Same die, identical electrical specs and pinout; differs only in tape-and-reel packaging and RoHS compliance (EUD+ includes lead-free finish and green marking). | No functional difference; EUD+ replaces EUD in new designs requiring RoHS-6 compliance and JEDEC-standard moisture sensitivity level (MSL3). | Select MAX9202EUD+ for production builds requiring RoHS compliance, traceability, and extended shelf-life handling per J-STD-020. |
| LM393DR | Single comparator, no latch, 1.3µs propagation delay, 0.8mW power; lacks dual-channel timing match, TTL latch interface, and rail-inclusive input range. | Suitable only for non-critical, low-speed threshold detection (e.g., battery low-voltage warning); cannot replace MAX9202EUD+ in latch-dependent or high-speed sampling roles. | Use LM393DR only in cost-sensitive, low-frequency applications where 7ns timing, latch control, and dual-channel synchronization are unnecessary. |
Compared with MAX9202EUD+, the MAX9202EUD offers identical functionality but lacks RoHS-6 compliance and MSL3 qualification, while the LM393DR falls short in speed, channel count, latch capability, and input range-making it unsuitable for any application requiring the precise timing or dual-latched behavior of the MAX9202EUD+.

FAQ
What is the maximum operating temperature range for the MAX9202EUD+?
The MAX9202EUD+ is specified for continuous operation from –40°C to +85°C. This industrial-grade temperature range is fully guaranteed by design and verified across all electrical parameters including propagation delay, input offset voltage, and latch timing. The device's junction temperature limit is +150°C, allowing margin for transient thermal excursions in high-density PCB layouts. All production units undergo 100% testing at +25°C, with design validation covering the full –40°C to +85°C range.
Does the MAX9202EUD+ support single-supply operation?
Yes, the MAX9202EUD+ supports true single-supply operation with VEE tied to ground and VCC set between +5V and +10V. In this configuration, its analog input common-mode range extends from 0V (GND) to VCC – 2.25V, enabling ground-referenced signal sensing. The digital supply VDD remains fixed at +5V. This mode is explicitly validated in the datasheet's "Typical Power-Supply Alternatives" section (Figure 1b) and confirmed in the Absolute Maximum Ratings table.
What is the function of pins 6 and 13 on the MAX9202EUD+?
Pins 6 and 13 on the MAX9202EUD+ are marked N.C. (No Connection) in the official pin description table and must remain unconnected. These pins have no internal bond wire or circuit connection and serve only as mechanical alignment aids in the TSSOP-14 package. Connecting them to any voltage or ground violates Maxim's recommended layout guidelines and may cause unpredictable behavior due to parasitic coupling or package stress effects.
How does the latch feature work on the MAX9202EUD+?
The MAX9202EUD+ features two independent TTL-compatible latch inputs (LATCHA on pin 4, LATCHB on pin 11). When either input is driven low, the corresponding comparator output freezes in its current logic state and ignores further input transitions until the latch input returns high. The latch release timing is characterized as tPD+(D) ≤ 10ns and tPD–(D) ≤ 10ns. This behavior is confirmed in the Timing Characteristics table and Applications Information section, and applies only to the MAX9202/MAX9203-not the MAX9201.
What decoupling capacitors are recommended for the MAX9202EUD+?
Maxim specifies 100nF ceramic capacitors placed as close as possible to each power pin: one between VCC and VEE, one between VDD and GND, and optionally a second 100nF cap between VCC and GND if VEE = GND in single-supply mode. These values are derived from the "Circuit Layout" section, which emphasizes low-inductance grounding and minimizes trace length to suppress high-frequency noise coupling into the comparator's sensitive analog inputs. Larger bulk capacitors (e.g., 1µF tantalum) are not required per datasheet guidance.
