Product details
Overview
The MAX9692ESE-T from Maxim Integrated is a single-channel, ultra-fast ECL-output comparator with latch-enable functionality, designed for high-speed signal conditioning in RF and digital test systems. It delivers 1.2ns typical propagation delay, 100ps skew, 150ps dispersion, and operates from +5V and -5.2V supplies. Its open-emitter outputs drive 50Ω-terminated transmission lines and support >600MHz signal processing in threshold detection and high-speed triggering applications.
For engineers reviewing the MAX9692ESE-T datasheet, MAX9692ESE-T pinout, MAX9692ESE-T application, or MAX9692ESE-T equivalent, key selection criteria include latch-enable timing (0.5ns setup/hold), ECL-compatible differential inputs, dual ground pins (GND1/GND2) for input/output stage isolation, and SO-16 narrow package thermal performance under continuous 36mA supply current.
Technical Context
The MAX9692ESE-T implements a BiCMOS-based ECL comparator core with separate input-stage (GND1) and output-stage (GND2) ground references to minimize coupling between high-gain analog front-end and fast switching output drivers. Its latch-enable (LE) input enables sample-hold operation with precise 0.5ns minimum pulse width and 1.0ns typical latch-enable delay, supporting synchronous acquisition in time-critical measurement systems.
It requires external 50Ω–200Ω pull-down resistors to -2.0V or 240Ω–2000Ω to -5.2V on open-emitter outputs (Q OUT/Q OUT), and mandates microstrip PCB layout with ground plane and local 0.01µF ceramic decoupling at VCC/VEE pins to maintain stability at >600MHz operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.2ns typical - enables sub-1ns decision timing for 1GHz+ sampling systems |
| Propagation Delay Skew | 100ps - ensures matched Q/Q OUT transitions critical for differential clock recovery |
| Latch Setup Time | 0.5ns - defines minimum input stability window before LE falling edge for reliable capture |
| Supply Voltages | +5V and -5.2V - standard ECL rail configuration compatible with legacy logic families |
| Input Offset Voltage | ±11.5mV max - supports accurate threshold detection down to ~10mV overdrive |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade embedded instrumentation |
| Package | 16-pin narrow SO (SOIC-N) - 10.3mm × 5.3mm footprint with 1.27mm pitch for dense RF layouts |
Pinout & Package
The MAX9692ESE-T is housed in a 16-pin narrow SO (SOIC-N) package with exposed pad not electrically connected. Pin 1 is VCC; pins 4 and 16 are VEE and GND respectively; pins 2–3 are IN+/IN-; pins 5–6 are Q OUT/Q OUT; pin 7 is LE; pins 8–15 include N.C., GND1, GND2, and reserved positions per functional diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply | Bypassed to GND with 0.1µF capacitor; powers internal bias and logic circuits |
| IN+ (Pin 2) | Differential positive input | Accepts ECL-level signals; referenced to GND1 for optimal common-mode rejection |
| IN- (Pin 3) | Differential negative input | Paired with IN+; differential input range spans -2.5V to +3.0V |
| VEE (Pin 4) | Negative supply | Bypassed to GND with 0.1µF capacitor; sets ECL output swing reference |
| Q OUT (Pin 5) | True output | Open-emitter output requiring external pull-down resistor to VT (-2V or -5.2V) |
| Q OUT (Pin 6) | Complementary output | Provides inverted logic state; matches Q OUT timing within 100ps skew |
| LE (Pin 7) | Latch-enable control | ECL-low forces outputs into stable state; ECL-high enables normal comparison |
| GND1 (Pin 8) | Input-stage ground | Biases differential input pair; must connect to solid ground plane separately from GND2 |
| GND2 (Pin 15) | Output-stage ground | References ECL output drivers; isolation from GND1 reduces supply-induced jitter |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low propagation delay | 1.2ns typical enables real-time decision making in >600MHz signal paths |
| Dual independent grounds | GND1 (input) and GND2 (output) reduce crosstalk and improve transient immunity |
| Latch-enable precision timing | 0.5ns setup/hold and 0.5ns minimum pulse width support deterministic sampling |
| ECL-compatible differential I/O | Fully compatible with standard ECL logic levels and 50Ω transmission line driving |
| High CMRR and PSRR | 80dB common-mode rejection and 60dB power-supply rejection ensure noise resilience |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast ECL comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9692ESE+ | Lead-free/RoHS-compliant version with identical electrical specs and SO-16 packaging | No functional difference; required for EU/China RoHS-regulated production | Select MAX9692ESE+ when compliance certification is mandatory; otherwise MAX9692ESE-T remains fully interchangeable |
| LMH7322MA/NOPB | Dual-channel, 3.3V single-supply, 1.5ns delay, no latch-enable; CMOS outputs require level-shifting for ECL systems | Suitable for lower-voltage, non-latched high-speed comparison where ECL compatibility is not required | Choose LMH7322MA/NOPB only if system uses 3.3V logic and latch function is unnecessary; not drop-in for MAX9692ESE-T |
Compared with MAX9692ESE+, the base MAX9692ESE-T offers identical performance without RoHS constraints, while LMH7322MA/NOPB provides dual-channel capability at lower voltage but lacks latch-enable and ECL output compatibility-making it unsuitable for direct replacement in legacy ECL infrastructure.

FAQ
What is the recommended power supply bypassing scheme for MAX9692ESE-T?
MAX9692ESE-T requires 0.1µF ceramic capacitors placed as close as possible to both VCC (Pin 1) and VEE (Pin 4), connected to a solid ground plane. Additional bulk capacitance (e.g., 10µF tantalum) may be used near the power entry point. GND1 (Pin 8) and GND2 (Pin 15) must connect independently to the same ground plane to preserve separation between input and output return paths. This layout minimizes supply-induced jitter and maintains 1.2ns propagation delay integrity.
How does the latch-enable (LE) function operate in MAX9692ESE-T?
In MAX9692ESE-T, the LE input controls sample-hold behavior: when LE is ECL-high, the device functions as a standard comparator; when LE transitions ECL-low, outputs freeze in an unambiguous ECL state determined by input conditions at that instant. The MAX9692ESE-T specifies 0.5ns minimum LE pulse width and 0.5ns setup/hold times. If unused, LE must be tied to ground, and its complementary node (not present on MAX9692ESE-T) is irrelevant.
What are the output interface requirements for MAX9692ESE-T?
MAX9692ESE-T features open-emitter outputs (Q OUT and Q OUT) requiring external pull-down resistors. For VT = -2.0V, use 50Ω–200Ω; for VT = -5.2V, use 240Ω–2000Ω. Outputs are fully ECL-compatible and drive 50Ω-terminated lines directly. No internal termination exists-external resistors define logic thresholds and slew rate. Improper pull-down values cause VOL/VOH shift and increased dispersion beyond the specified 150ps.
Can MAX9692ESE-T be used in AC-coupled high-speed applications?
Yes, MAX9692ESE-T supports AC-coupled inputs with proper DC biasing. Its input common-mode range is -2.5V to +3.0V, allowing use with capacitive coupling followed by a Thevenin divider to set VCM near 0V. However, input slew rate must exceed 1V/µs for clean switching without oscillation-especially critical in AC-coupled configurations where transient settling affects decision accuracy. Layout with microstrip routing and ground plane is mandatory.
What is the thermal performance of MAX9692ESE-T in its SO-16 package?
The MAX9692ESE-T in 16-pin narrow SO package has a thermal resistance θJA of 1066.7°C/W (derating 13.3mW/°C above +70°C), with 1066.7mW maximum continuous power dissipation at TA = +70°C. At full 36mA supply current and ±5.2V/5V rails, power dissipation is ~360mW-well within safe operating limits. For sustained high-temperature operation (>70°C), ensure ≥2 sq-in copper area under the package and avoid adjacent heat sources to prevent junction temperature exceeding +150°C.
