Product details
Overview
The MAX9201EUE-T from Maxim Integrated is a quad voltage comparator IC with TTL-compatible outputs, 7ns typical propagation delay at 5mV overdrive, ±5V or +5V to +10V analog supply range, and 9mW per comparator power consumption. It operates across -40°C to +85°C and is used in high-speed A/D converters, line receivers, and signal restoration circuits where precise threshold detection and fast response are required.
For engineers reviewing the MAX9201EUE-T datasheet, MAX9201EUE-T pinout, MAX9201EUE-T application, or MAX9201EUE-T equivalent, this device serves as a low-power, high-speed replacement for legacy comparators in mixed-signal timing-critical systems requiring ground-sensing inputs and separate analog/digital supply domains.
Technical Context
The MAX9201EUE-T implements four independent bipolar comparators with rail-to-rail input common-mode range extending to the negative supply (VEE), enabling true ground-referenced sensing under single-supply operation. Each channel features active internal pullup on its TTL output stage, eliminating external resistors.
It supports flexible power architecture: analog supplies VCC (4.75V–10.5V) and VEE (typically –5V or GND), plus digital supply VDD (4.75V–5.25V). Unlike MAX9202/MAX9203, it lacks latch inputs-making it transparent-only with no output hold functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 7ns typical (5mV overdrive, CL = 15pF); enables sampling at >100MHz effective rates in A/D front-ends. |
| Input Offset Voltage | 7.5mV max (–40°C to +85°C); ensures stable threshold accuracy without trimming in industrial temperature ranges. |
| Analog Supply Range | VCC–VEE = 4.75V to 10.5V; supports ±5V split or +5V/+10V single-supply configurations with VEE = GND. |
| Power Consumption | 9mW per comparator at +5V supply; reduces thermal load in dense PCB layouts and battery-sensitive designs. |
| Input Common-Mode Range | Extends to VEE – 0.1V; allows direct ground-level input detection without level-shifting circuitry. |
| Output Drive | VOH = 3.0V min (1mA source), VOL = 0.4V max (8mA sink); compatible with standard LS-TTL and 74HC logic families. |
| Supply Rejection | PSRR = 250 µV/V (–40°C to +85°C); maintains stable switching thresholds despite digital supply noise coupling. |
Pinout & Package
MAX9201EUE-T is housed in a 16-pin TSSOP package (3.0mm × 4.4mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin numbering follows JEDEC MO-153 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN_– | Negative input terminals for comparators A, B, C, D - referenced to VEE, support rail-to-rail common-mode swing. |
| 2, 7, 10, 15 | IN_+ | Positive input terminals for comparators A, B, C, D - matched to IN_– for precision differential thresholding. |
| 3 | GND | Digital ground reference for VDD and TTL output stages; must be isolated from analog ground (VEE) in mixed-signal layouts. |
| 4, 5, 12, 13 | OUT_ | TTL-compatible open-collector outputs with internal pullups; drive directly into LS-TTL loads without external resistors. |
| 6 | VEE | Negative analog supply and substrate connection; tied to GND for single-supply operation or –5V for split-rail systems. |
| 11 | VDD | +4.75V to +5.25V digital supply for output stage and internal logic; decoupling required within 1cm of pin. |
| 14 | VCC | +4.75V to +10.5V positive analog supply; powers input stages and sets input dynamic range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Includes VEE – 0.1V, enabling ground-sensing in single-supply systems without input bias networks. |
| 7ns propagation delay (5mV overdrive) | Supports clean edge detection in high-frequency clock recovery and data slicing applications up to ~140MHz. |
| Separate analog/digital supplies | Isolates noise-sensitive analog inputs from noisy digital switching domains via dedicated VEE/GND separation. |
| Internal TTL pullup outputs | Eliminates need for four external 1kΩ–4.7kΩ pullup resistors, reducing BOM count and board area in quad-channel designs. |
| Low 9mW/comparator power | Enables integration of four comparators in thermally constrained spaces such as portable instrumentation and optical modules. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Slower (1.3µs propagation delay), no internal pullups, wider supply range (2V–36V), no latch capability. | Suitable for general-purpose, non-timing-critical threshold detection; not viable for >1MHz signal restoration. | Select LM339DR only when cost sensitivity outweighs speed/power requirements and external pullups are acceptable. |
| TLV3501CDR | Faster (4.5ns delay), CMOS input (pA bias current), rail-to-rail output, but requires external pullup and lacks VEE support. | Better for low-input-current sensor interfaces; cannot sense below GND without level shifting due to input range limitation. | Choose TLV3501CDR when ultra-low input bias and sub-5ns delay are mandatory, and ground-referenced negative inputs are not needed. |
Compared with LM339DR and TLV3501CDR, the MAX9201EUE-T uniquely combines 7ns speed, internal TTL pullups, and true ground-sensing capability in a single quad package-making it optimal for space-constrained, mixed-supply high-speed data acquisition systems where layout simplicity and deterministic timing are critical.

FAQ
What is the maximum operating frequency supported by the MAX9201EUE-T?
The MAX9201EUE-T does not specify a maximum operating frequency directly, but its 7ns typical propagation delay at 5mV overdrive implies reliable operation with input signal edges faster than ~140MHz. For clean square-wave output generation, system-level bandwidth is limited by load capacitance and PCB layout; measured response time remains under 12ns across –40°C to +85°C per the datasheet timing characteristics. Real-world usable frequency depends on overdrive level and termination-MAX9201EUE-T has been validated in 100MHz sine-wave discrimination applications.
Does the MAX9201EUE-T support single-supply operation?
Yes, the MAX9201EUE-T supports single-supply operation with VEE tied to GND and VCC set between +4.75V and +10.5V. Its input common-mode range extends to VEE – 0.1V, allowing direct ground-referenced input sensing. The digital supply VDD must still be +4.75V to +5.25V. This configuration is explicitly validated in Figure 1b of the datasheet and used in line receiver and PWM monitor applications where negative supply rails are unavailable.
Are there internal pullup resistors on the MAX9201EUE-T outputs?
Yes, the MAX9201EUE-T integrates active internal pullup circuitry on all four TTL-compatible outputs (pins 4, 5, 12, 13), eliminating the need for external pullup resistors. This feature reduces component count and board area in quad-comparator implementations. Output high voltage is specified as 3.0V minimum at 1mA source current, confirming functional pullup strength sufficient for LS-TTL and 74HC fanout.
What is the difference between MAX9201EUE-T and MAX9202EUD?
The MAX9201EUE-T is a quad comparator without latch inputs, while the MAX9202EUD is a dual comparator with TTL-compatible latch inputs (pins 4 and 11) that freeze output states when driven low. MAX9201EUE-T uses a 16-pin TSSOP package and provides four independent transparent comparators; MAX9202EUD uses a 14-pin TSSOP and offers latched operation for sampled-data systems. Neither is pin-compatible-their pinouts, channel count, and feature sets differ fundamentally.
Can the MAX9201EUE-T be used with ±5V supplies?
Yes, the MAX9201EUE-T is fully specified for ±5V operation: VCC = +5V, VEE = –5V, VDD = +5V. This split-supply mode enables symmetric input voltage ranges (–5V to +5V) and is validated in the Absolute Maximum Ratings and Electrical Characteristics tables. Figure 1c in the datasheet confirms this configuration, and parameters like input offset voltage and propagation delay are guaranteed across –40°C to +85°C under ±5V conditions-making MAX9201EUE-T suitable for legacy industrial systems using bipolar supplies.
