Product details
Overview
The MAX962ESA-T from Maxim Integrated is a dual ultra-high-speed comparator optimized for single +3V or +5V operation, featuring 4.5ns propagation delay (5mV overdrive), 5mA supply current per comparator, and Beyond-the-Rails™ input range extending 100mV beyond both rails. It drives TTL/CMOS loads with outputs sinking or sourcing 4mA to within 0.52V of GND or VCC, and is used in GPS receivers, high-speed sampling circuits, and line receivers.
For engineers reviewing the MAX962ESA-T datasheet, MAX962ESA-T pinout, MAX962ESA-T application, or MAX962ESA-T equivalent, key selection criteria include propagation delay vs. overdrive, rail-to-rail input capability, output drive strength at 3V/5V, and SO-8 package compatibility for space-constrained industrial timing and signal conditioning designs.
Technical Context
The MAX962ESA-T implements a current-driven output stage enabling fast slew rates while maintaining low static power; its internal 3.5mV hysteresis eliminates external feedback components and prevents oscillation near trip points. Input protection includes dual 200Ω resistors and diode clamps limiting differential voltage to ≤2.1V.
Unlike latch-equipped variants (MAX961/MAX963), the MAX962ESA-T has no latch-enable or shutdown functionality-its dual comparators operate continuously with independent IN+/IN− pairs and open-collector–compatible TTL/CMOS outputs. Propagation delay skew between channels is guaranteed ≤0.3ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision timing in high-frequency sampling and clock recovery. |
| Supply Voltage Range | +2.7V to +5.5V - supports direct integration into 3V and 5V logic domains without level-shifting. |
| Input Common-Mode Range | –0.1V to VCC + 0.1V - accepts signals beyond supply rails, simplifying sensor interface in battery-powered systems. |
| Output Drive Strength | Sinks/sources 4mA to within 0.52V of GND/VCC - directly drives standard TTL/CMOS inputs without pull-up resistors. |
| Input-Referred Hysteresis | 3.5mV - suppresses noise-induced chatter without external components, critical for clean threshold detection. |
| Supply Current per Comparator | 5mA typical at VCC = 5V - balances speed and power for portable instrumentation and RF front-end monitoring. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and communications equipment. |
Pinout & Package
The MAX962ESA-T is housed in an 8-pin SO (Small Outline) package with exposed pad not present; footprint matches JEDEC MS-012AC standard. Pin 1 is top-left corner marker (dot or notch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA− | Inverting input for comparator A - differential pair node accepting signals up to 100mV beyond rails. |
| 2 | INA+ | Noninverting input for comparator A - referenced against INA− to determine output polarity. |
| 3 | GND | Analog/digital ground reference - must connect to low-inductance PCB ground plane for stable high-speed operation. |
| 4 | INB− | Inverting input for comparator B - electrically isolated from channel A; supports independent dual-threshold sensing. |
| 5 | INB+ | Noninverting input for comparator B - enables simultaneous comparison of two signal pairs. |
| 6 | VCC | Positive supply input - requires local 0.1µF ceramic decoupling capacitor placed adjacent to pin. |
| 7 | QA | Comparator A TTL output - active-low compatible; sinks 4mA to 0.52V above GND when asserted. |
| 8 | QB | Comparator B TTL output - independently controlled; no shared logic or timing dependency with QA. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 4.5ns ensures precise timing alignment in >200MHz sampling clocks and pulse-width discriminators. |
| Beyond-the-Rails input range | –0.1V to VCC + 0.1V allows direct connection to unbuffered sensors or op-amp outputs exceeding supply limits. |
| TTL/CMOS-compatible outputs | Active-low outputs drive standard logic families without external pull-ups, reducing BOM count and board area. |
| Internal 3.5mV hysteresis | Eliminates need for external positive feedback resistors, improving layout simplicity and thermal stability. |
| Low-voltage single-supply operation | Functional down to +2.7V enables use in Li-ion powered devices and low-power IoT edge nodes. |
Applications
| GPS Receivers | High-Speed Sampling Circuits |
|---|---|

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 |
|---|---|---|---|
| LMH7322MA/NOPB | Higher 2.3ns propagation delay, 6mA supply current, no internal hysteresis, requires external feedback. | Used in RF test equipment where sub-3ns timing dominates over power and component count. | Select when absolute minimum delay outweighs need for integrated hysteresis and lower quiescent current. |
| ADCMP602BRMZ-REEL | 4.5ns delay, 5.5mA supply, 2.5mV hysteresis, same SO-8 package, but only single-channel per unit. | Requires two units for dual-channel function, increasing board area and cost versus single MAX962ESA-T. | Choose if design already uses ADCMP602 elsewhere and board layout accommodates dual placement. |
Compared with LMH7322MA/NOPB and ADCMP602BRMZ-REEL, the MAX962ESA-T uniquely delivers dual-channel operation, integrated 3.5mV hysteresis, and 5mA supply current in one SO-8 package-reducing component count and layout complexity for compact, noise-immune threshold detection systems.

FAQ
What is the maximum operating supply voltage for the MAX962ESA-T?
The MAX962ESA-T supports a supply voltage range of +2.7V to +5.5V. Absolute maximum rating is +6V on VCC relative to GND. Operation above +5.5V risks permanent damage and violates the specified electrical characteristics; designs must ensure VCC remains within this window under all conditions including transients and ripple.
Does the MAX962ESA-T include shutdown or latch functionality?
No, the MAX962ESA-T does not include shutdown or latch-enable features. Unlike the MAX961/MAX963/MAX964/MAX997 variants, it operates continuously with fixed dual-comparator topology. Its pinout omits SHDN and LE pins, and datasheet specifications confirm absence of these functions - making it ideal for always-on, low-latency threshold detection where power cycling or output hold is unnecessary.
What is the input common-mode voltage range specification for the MAX962ESA-T?
The MAX962ESA-T features a Beyond-the-Rails™ input common-mode range of –0.1V to VCC + 0.1V. This means either input (INA+, INA−, INB+, INB−) can be driven 100mV below GND or 100mV above VCC without false output inversion, provided the other input remains within that same extended range. This capability simplifies interfacing with op-amps, sensors, or DACs operating outside the supply rails.
Can the MAX962ESA-T drive standard TTL or CMOS logic directly?
Yes, the MAX962ESA-T provides TTL/CMOS-compatible outputs. Each output (QA, QB) can sink or source 4mA while maintaining VOH ≥ VCC – 0.52V and VOL ≤ 0.52V, meeting standard TTL high/low voltage thresholds at both 3V and 5V supplies. No external pull-up resistors are required, enabling direct connection to 74HC, 74AHC, or microcontroller GPIO pins.
What package type and pin count does the MAX962ESA-T use?
The MAX962ESA-T uses an 8-pin SO (Small Outline) package conforming to JEDEC MS-012AC outline. It is not the μMAX® variant (which carries suffix -T in "EUA-T"); the "ESA" suffix explicitly denotes the SO-8 body. Pin 1 is marked by a dot or notch at the top-left corner, and the package is RoHS-compliant with lead-free terminations.
