Product details
Overview
MAX9202ESD+T 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), ±5V analog supply capability, and consumes only 4.0mA total analog supply current (ICC + IEE) at +5V/+5V/-5V operation - enabling use in high-speed A/D converters, line receivers, and PWM circuits.
For engineers reviewing the MAX9202ESD+T datasheet, MAX9202ESD+T pinout, MAX9202ESD+T application, or MAX9202ESD+T equivalent, this device is selected for low-jitter threshold detection where latch-hold functionality, rail-to-rail input common-mode range (including negative rail), and TTL-level interfacing to legacy logic are required.
Technical Context
The MAX9202ESD+T implements two independent bipolar comparators with active internal pullups and separate analog (VCC/VEE) and digital (VDD) supply domains. Its input stage supports common-mode voltages down to VEE − 0.1V, enabling ground-sensing operation with single-supply configurations (e.g., VEE = GND, VCC = +5V to +10V).
Latch control is implemented via dedicated TTL-compatible inputs (LATCHA/LATCHB) that freeze output states on falling edge; latch disable delays are 10ns typical. Propagation delay matching between channels is tightly controlled (∆tPD ≤ 2.5ns over temperature), critical for synchronized sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD±) | 7ns typ (5mV overdrive, CL = 15pF) - enables sub-100MHz sampling decision timing. |
| Analog Supply Range | +5V to +10V (VCC) and −5V to 0V (VEE) - supports single-supply (0V/5V) or split-supply (±5V) operation. |
| Digital Supply (VDD) | +4.75V to +5.25V - ensures compatibility with standard TTL/CMOS logic interfaces. |
| Input Offset Voltage (VOS) | 7.5mV max (−40°C to +85°C) - defines minimum detectable differential signal without calibration. |
| Output Drive Capability | VOH ≥ 3.0V @ 1mA sink, VOL ≤ 0.4V @ 8mA source - directly drives 74LS/TTL loads with fan-out of four. |
| Latch Input Thresholds | VLH = 1.4–2.0V, VLL = 0.8–1.4V - compatible with standard TTL logic levels for reliable hold/release control. |
| Power Dissipation | 24mW typ (VCC = VDD = +5V, VEE = −5V) - enables thermally constrained PCB layouts in dense signal chains. |
Pinout & Package
MAX9202ESD+T is housed in a 14-pin narrow SO (Small Outline) package with exposed pad (not electrically connected). Pin assignments are optimized for noise isolation: analog supplies (VCC, VEE), digital supply (VDD), and ground (GND) are physically separated; input and output pins are arranged to minimize crosstalk.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN_− (A, B) | Negative input terminals for comparator channels A and B - referenced to VEE; support common-mode down to VEE − 0.1V. |
| 2, 9 | IN_+ (A, B) | Positive input terminals for comparator channels A and B - matched pair with IN_− for differential sensing. |
| 3 | GND | Digital ground reference - isolated from analog substrate (VEE) to prevent digital noise coupling into analog path. |
| 4, 11 | LATCH_ (A, B) | TTL-compatible latch enable inputs - low level freezes output state; high level enables transparent comparison. |
| 5, 12 | OUT_ (A, B) | TTL logic outputs with internal pullup - drive 74LS loads directly; no external pullup required. |
| 6, 13 | N.C. | No internal connection - must be left floating or grounded per layout best practices. |
| 7 | VEE | Negative analog supply and substrate connection - sets lower bound of input common-mode range and analog bias point. |
| 10 | VDD | +5V digital supply - powers output stage and latch logic; decoupling capacitor required adjacent to pin. |
| 14 | VCC | Positive analog supply - powers input stage and internal bias; separate decoupling from VDD mandatory. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VEE − 0.1V, enabling ground-referenced sensing with single +5V supply (VEE = GND). |
| Matched propagation delay between channels | ∆tPD ≤ 2.5ns over full temperature range - ensures synchronous decision timing across dual channels. |
| Integrated latch control with TTL thresholds | Eliminates need for external flip-flops in sampled-data systems; reduces component count and board area. |
| Separate analog/digital supply domains | Prevents digital switching noise from modulating analog input offset or propagation delay. |
| Low 24mW total power dissipation | Reduces thermal load in multi-comparator arrays and enables use in space-constrained industrial modules. |
Applications
| High-Speed A/D Converters | Line Receivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9202EUD+ | Same electrical specs, but in 14-pin TSSOP package - 3.5mm × 5mm footprint vs. SO's 3.9mm × 8.7mm; thinner profile. | Better suited for high-density PCBs where height clearance or thermal spread is constrained. | Select MAX9202EUD+ when board real estate or assembly reflow profile favors TSSOP over SO. |
| LM393DR | Slower (300ns propagation delay), no latch, single supply only (2–36V), higher power (0.4mW/comparator), no separate VDD. | Applicable only in non-critical timing, low-cost consumer systems where speed and latch function are unnecessary. | Choose LM393DR only for cost-sensitive, low-frequency (<100kHz) threshold detection without synchronization requirements. |
Compared with MAX9202ESD+T, MAX9202EUD+ offers identical performance in a smaller, thermally superior package, while LM393DR trades speed, latch capability, and supply flexibility for extreme cost reduction - making it unsuitable for any application requiring sub-10ns timing fidelity or synchronized sampling.

FAQ
What is the maximum operating temperature range for the MAX9202ESD+T?
The MAX9202ESD+T is rated for continuous operation from −40°C to +85°C. This extended industrial temperature range is validated across all key parameters including propagation delay, input offset voltage, and latch timing - ensuring reliability in factory automation, motor drives, and outdoor instrumentation where ambient temperatures fluctuate widely. The MAX9202ESD+T maintains its 7ns typical propagation delay specification across this full range.
Can the MAX9202ESD+T operate from a single +5V supply?
Yes, the MAX9202ESD+T supports single-supply operation with VEE tied to ground and VCC at +5V, while VDD remains at +5V. In this configuration, the input common-mode range extends from ground to VCC − 2.25V (i.e., 0V to +2.75V), enabling ground-referenced signal detection. The MAX9202ESD+T retains full latch functionality and TTL output compatibility under single-supply conditions, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables.
Does the MAX9202ESD+T require external pull-up resistors on its outputs?
No, the MAX9202ESD+T features active internal pull-ups on its TTL outputs, eliminating the need for external pull-up resistors. Each output can source up to 1mA while maintaining VOH ≥ 3.0V and sink up to 8mA while holding VOL ≤ 0.4V - meeting standard TTL logic thresholds without additional components. This integrated design reduces BOM count and PCB area, and ensures consistent rise/fall times (2.0ns/1.0ns typical) across process and temperature variations.
How does the latch function work on the MAX9202ESD+T?
The MAX9202ESD+T provides two independent TTL-compatible latch inputs (LATCHA and LATCHB) that control output transparency. When a latch input is held high, the comparator operates transparently - output follows input changes with 7ns delay. When driven low, the output state is latched immediately and held regardless of subsequent input transitions. Minimum setup/hold times (2ns/1ns) and latch-disable delays (10ns) are specified to ensure robust timing in synchronous digital systems using the MAX9202ESD+T.
What is the input impedance of the MAX9202ESD+T?
The MAX9202ESD+T exhibits a differential input impedance of 5MΩ and a common-mode input impedance of 5.5MΩ, measured at the IN_+/IN_− pins. These values remain stable across the full −40°C to +85°C operating range and are independent of supply voltage within the specified analog and digital ranges. This high impedance minimizes loading on precision sensor front-ends and high-impedance voltage dividers, preserving signal integrity in measurement applications using the MAX9202ESD+T.
