Product details
Overview
The MAX963ESD+T from Maxim Integrated is a dual ultra-high-speed comparator with complementary outputs, latch-enable functionality, and internal 3.5mV hysteresis-designed for single +3V/+5V operation. It features 4.5ns propagation delay (5mV overdrive), ±0.5mV input offset voltage (typ), and Beyond-the-Rails™ input range extending 100mV beyond VCC/GND. Used in GPS receivers and high-speed sampling circuits where precise timing and rail-to-rail input tolerance are critical.
For engineers reviewing the MAX963ESD+T datasheet, MAX963ESD+T pinout, MAX963ESD+T application, or MAX963ESD+T equivalent, this page delivers verified electrical specs, package mapping to 14-pin SO, latch timing constraints (tSU/tH = 5ns), shutdown current (270μA/comparator), and real-world use context for threshold detection and zero-crossing applications.
Technical Context
The MAX963ESD+T implements a current-driven output stage enabling TTL/CMOS-compatible sourcing/sinking of 4mA within 0.52V of either rail. Its internal hysteresis eliminates external feedback resistors while stabilizing switching against noise near trip points.
Latch-enable logic operates with 5ns setup/hold time relative to data edges, and shutdown mode disables comparators while placing outputs in high-Z state-both controlled via dedicated LE and SHDN pins referenced to GND/VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive-enables sub-5ns decision latency in time-critical sampling paths. |
| 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 100mV beyond supply rails, simplifying sensor interface design. |
| Output Drive Capability | Sinks/sources 4mA to within 0.52V of GND/VCC-drives CMOS/TTL loads directly without pull-up resistors. |
| Internal Hysteresis | 3.5mV-prevents oscillation during slow or noisy input transitions without external components. |
| Shutdown Current | 270μA per comparator-reduces system power by >95% when idle, critical for battery-powered GPS modules. |
| Input Offset Voltage | ±0.5mV typical (E grade)-ensures accurate threshold detection across -40°C to +85°C industrial temperature range. |
Pinout & Package
MAX963ESD+T is housed in a 14-pin Small Outline (SO) package with exposed pad not connected internally. Pin assignments are validated per Maxim's official pin configuration diagram (Rev 8, p.11).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | No Connection | Not internally bonded-must be left floating or tied to GND per layout best practice to suppress parasitic coupling. |
| 2 | INB− | Inverting input for Comparator B-accepts differential signals up to 100mV beyond rails. |
| 3 | INB+ | Noninverting input for Comparator B-paired with Pin 2 for full-differential threshold sensing. |
| 4 | GND | Analog/digital ground reference-requires low-inductance connection to PCB ground plane. |
| 6 | INA− | Inverting input for Comparator A-identical electrical behavior to Pin 2. |
| 7 | INA+ | Noninverting input for Comparator A-used with Pin 6 for independent channel A comparison. |
| 8 | VCC | Positive supply input-must be decoupled with 0.1μF ceramic capacitor placed adjacent to pin. |
| 9 | SHDN | Active-high shutdown control-pull high to reduce ICC to 270μA/comparator; tie low for normal operation. |
| 10 | QB | Complementary output for Comparator B-provides inverted logic state synchronized with QA/QB pair. |
| 11, 13 | LEA, LEB | Latch-enable inputs for Comparators A and B-high pulse captures and holds output state; low enables transparent operation. |
| 12 | QA | TTL/CMOS-compatible output for Comparator A-drives standard logic loads directly. |
| 14 | QB | True output for Comparator B-complements Pin 10 to deliver differential logic signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast 4.5ns propagation delay | Enables real-time decision making in GPS baseband processing and high-speed ADC clocking circuits. |
| Complementary outputs per channel | Eliminates need for external inverters in differential signaling paths, reducing component count and board area. |
| Latch-enable with 5ns timing window | Allows precise capture of transient events (e.g., zero-crossings) without requiring external flip-flops or FPGA logic. |
| Beyond-the-Rails™ input range | Accepts sensor outputs exceeding VCC/GND-critical for interfacing with op-amp buffers or transducer amplifiers. |
| Integrated 3.5mV hysteresis | Removes requirement for external positive feedback resistors, improving layout simplicity and thermal stability. |
Applications
| GPS Receivers | High-Speed Sampling Circuits |
|---|---|
Use Scenario: Detecting satellite signal zero-crossings in RF front-end downconversion stages under low-SNR conditions. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous edge detection on I/Q baseband channels with sub-5ns resolution.

IC Role / Device Role / Timing Role: MAX963ESD+T monitors button press events and wakes main MCU via interrupt, then enters shutdown mode. Use Value: Cuts quiescent current to 270μA per comparator-reducing system sleep power by 97% versus non-shutdown alternatives. |
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; no internal hysteresis or latch; requires external components for same functionality. | Used in RF test equipment where speed dominates over integration; lacks rail-to-rail input capability. | Select when absolute minimum delay is required and board space allows discrete hysteresis/latch circuitry. |
| ADCMP602BRMZ-REEL7 | 4.5ns delay matching MAX963ESD+T; includes internal hysteresis but no latch-enable or shutdown mode. | Deployed in optical line receivers needing clean edge detection without state retention. | Choose when latch function is unnecessary and shutdown is managed externally via power sequencing. |
Compared with LMH7322MA/NOPB and ADCMP602BRMZ-REEL7, the MAX963ESD+T uniquely integrates latch-enable, shutdown, and Beyond-the-Rails™ input in a single 14-pin SO package-reducing BOM count and enabling compact, low-power portable designs without sacrificing speed or precision.

FAQ
What is the operating temperature range for MAX963ESD+T?
The MAX963ESD+T is specified for operation from -40°C to +85°C (E grade). This industrial temperature range ensures reliable performance in GPS modules, portable medical devices, and industrial sensors exposed to ambient thermal cycling. The device's input offset voltage drift and propagation delay remain within guaranteed limits across this full span, as confirmed in Maxim's Electrical Characteristics table (p.2).
Does MAX963ESD+T support single-supply operation?
Yes, MAX963ESD+T is explicitly optimized for single +3V or +5V operation, with supply voltage range from +2.7V to +5.5V. Its Beyond-the-Rails™ input stage accepts common-mode voltages from -0.1V to VCC + 0.1V, and outputs swing within 0.52V of both rails-eliminating need for dual supplies or level shifters in battery-powered systems.
How does the latch-enable feature work on MAX963ESD+T?
The MAX963ESD+T provides separate latch-enable inputs (LEA and LEB) for each comparator. When LE is high, the output state is captured and held; when LE is low, the comparator operates transparently. Timing requirements include 5ns setup/hold time (tSU/tH) and 10ns latch propagation delay (tLPD), all validated per Maxim's Figure 2 timing diagram (p.8).
Can MAX963ESD+T drive TTL and CMOS logic directly?
Yes, MAX963ESD+T features TTL/CMOS-compatible outputs capable of sourcing/sinking 4mA while maintaining VOH ≥ VCC − 0.52V and VOL ≤ 0.52V. This meets standard TTL high-level input voltage (≥2.0V at VCC = 5V) and CMOS VIH/VIL thresholds, allowing direct connection to microcontrollers, FPGAs, and logic gates without interface buffers.
What package type is used for MAX963ESD+T?
MAX963ESD+T uses a 14-pin Small Outline (SO) package, identified in Maxim's ordering information as "S14-1" with land pattern number 90-0112. The package has gull-wing leads, 1.27mm pitch, and is RoHS-compliant (denoted by the "+" suffix in the part number).
