Product details
Overview
MAX9693ESE from Maxim Integrated is a dual 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 channel-to-channel propagation match, and operates from +5V/-5.2V supplies. Its complementary ECL outputs drive 50Ω-terminated transmission lines and support >600MHz signal processing in threshold detection and high-speed triggering applications.
For engineers reviewing the MAX9693ESE datasheet, MAX9693ESE pinout, MAX9693ESE application, or MAX9693ESE equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternative parts with functional differences, and supply support details specific to the 16-pin narrow SO package.
Technical Context
The MAX9693ESE integrates two independent high-speed comparators sharing common power rails (+5V VCC, -5.2V VEE) and ground. Each channel features differential ECL-compatible inputs, open-emitter complementary outputs requiring external pull-down resistors (50Ω–200Ω to -2V or 240Ω–2000Ω to -5.2V), and dedicated latch-enable (LEA/LEB) inputs with defined logic thresholds (-1.1V VIH, -1.5V VIL).
Its BiCMOS process enables sub-2ns propagation delay with 150ps dispersion and 100ps skew between Q/Q outputs. The latch function allows sample-hold operation: when LE is low, outputs freeze in unambiguous ECL states determined at the latch edge, with 0.5ns setup/hold time and 0.5ns minimum pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.2ns typical - enables clean decision-making on signals with <1.7ns rise/fall times at 600MHz+ frequencies. |
| Channel Match (tPDM) | 100ps max - ensures synchronized timing across dual channels for parallel sampling or differential strobing. |
| Supply Voltages | +5V VCC / -5.2V VEE - requires dual-rail biasing; incompatible with single-supply or CMOS-level logic interfaces. |
| Output Type | Open-emitter ECL - mandates external pull-down resistors; output swing referenced to VT (-2V) for 50Ω termination. |
| Latch Enable Timing | 0.5ns setup/hold, 0.5ns pulse width - supports precise sub-nanosecond sampling windows in high-speed data acquisition. |
| Input Offset Voltage | ±11.5mV max - sets worst-case DC error floor for threshold accuracy in precision level-detection circuits. |
| Common-Mode Range | -2.5V to +3.0V - accommodates wide-swing ECL input signals while rejecting supply noise via 60dB CMRR. |
Pinout & Package
MAX9693ESE is housed in a 16-pin narrow SO (Small Outline) package, 3.9mm × 9.9mm body, 1.27mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Q OUTA / Q OUTA | Complementary open-emitter outputs for Channel A - require external pull-down to VT (-2V) for proper ECL logic levels. |
| 3, 14 | GND | Shared analog/digital ground reference - must connect to solid copper ground plane per layout guidelines. |
| 4 | LEB | Channel B latch-enable complementary input - driven low to latch Channel B output state; VIH = -1.1V, VIL = -1.5V. |
| 5 | LEB | Channel B latch-enable true input - paired with Pin 4; both required for differential latch control of Channel B. |
| 6 | VCC | +5V positive supply - bypass with 0.1µF ceramic capacitor close to pin to suppress high-frequency noise. |
| 7 | INB- | Negative input for Channel B - differential pair with Pin 8; accepts -2.5V to +3.0V common-mode range. |
| 8 | INB+ | Positive input for Channel B - forms high-gain differential stage; input bias current ≤30µA over temperature. |
| 9 | INB+ | Positive input for Channel B - redundant labeling confirms dual-input symmetry per channel. |
| 10 | INB- | Negative input for Channel B - matches Pin 7; differential input resistance ≥60kΩ ensures minimal loading. |
| 12 | LEA | Channel A latch-enable complementary input - identical electrical behavior to Pin 4 for Channel A control. |
| 13 | LEA | Channel A latch-enable true input - used with Pin 12 to enable sample-hold on Channel A outputs. |
| 15 | Q OUTB | Complementary open-emitter output for Channel B - mirrors Pin 1 behavior; same termination requirements. |
| 16 | Q OUTB | True open-emitter output for Channel B - completes differential output pair; VOH = -0.76V, VOL = -1.55V (typ). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables simultaneous threshold evaluation on two signals without cross-talk; 100ps channel match supports time-aligned sampling. |
| Latch-enable with differential LE inputs | Eliminates metastability in high-speed sampling by freezing outputs on precise latch edges; differential LE rejects common-mode noise. |
| 1.2ns propagation delay | Supports >600MHz signal bandwidths in receiver front-ends and peak detectors where timing resolution is critical. |
| ECL-compatible open-emitter outputs | Drives 50Ω transmission lines directly; output voltage swing (-1.06V to -1.89V) matches standard ECL logic families. |
| BiCMOS process technology | Combines bipolar speed with CMOS integration density - achieves sub-2ns delay while maintaining DC precision (±11.5mV VOS). |
Applications
| High-Speed Line Receivers | Peak Detectors |
|---|---|
|
Use Scenario: Recovering NRZ data from lossy backplane traces or coaxial cables operating above 500MHz. IC Role / Device Role / Timing Role: Dual-channel comparator acts as synchronous decision circuit, converting analog eye-diagram crossings into clean ECL logic levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ECL comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9692ESE | Single-channel version in same 16-pin SO package; shares identical propagation delay (1.2ns), latch timing, and supply specs. | Lacks second comparator channel; suitable only for single-signal thresholding or triggering where space or cost constraints eliminate need for dual functionality. | Select MAX9692ESE when system requires only one high-speed comparator and PCB area is constrained - same footprint but half the channel count. |
| ADCMP572BCPZ-R7 | Analog Devices part with 1.5ns propagation delay, 3.3V single supply, LVDS outputs; no latch-enable function. | Designed for lower-power, single-supply systems interfacing to FPGAs/ASICs; lacks sample-hold capability and ECL-level compatibility. | Choose ADCMP572BCPZ-R7 for 3.3V systems needing LVDS output compatibility and lower power (25mA vs 50mA), but accept absence of latch and ECL drive. |
Compared with MAX9693ESE, MAX9692ESE offers identical performance in a single-channel form factor ideal for space-constrained designs, while ADCMP572BCPZ-R7 trades ECL compatibility and latch functionality for LVDS output and single-supply operation - making it suitable for modern mixed-signal SoC interfaces but not legacy ECL systems.

FAQ
What is the correct termination scheme for MAX9693ESE outputs?
The MAX9693ESE outputs are open-emitter ECL and require external pull-down resistors. For -2V termination (VT), use 50Ω–200Ω resistors; for -5.2V termination, use 240Ω–2000Ω resistors. Incorrect termination causes invalid logic levels or excessive power dissipation. Always route outputs as microstrip with controlled impedance matching the load.
Does MAX9693ESE support single-supply operation?
No, MAX9693ESE requires dual supplies: +5V (VCC) and -5.2V (VEE). Its internal BiCMOS architecture and ECL output stage are incompatible with single-supply configurations. Attempting operation with only +5V or ground-referenced supplies will result in non-functional outputs and potential device damage.
How should unused comparator inputs be handled on MAX9693ESE?
Per the datasheet, unused comparator inputs on MAX9693ESE must not be left floating. Tie unused IN+/IN- pairs to valid common-mode voltages within -2.5V to +3.0V (e.g., -2V) using appropriate series resistors to prevent oscillation and excessive current draw caused by high gain-bandwidth product.
What is the function of the dual LE pins (e.g., Pins 4 & 5) on MAX9693ESE?
Pins 4 and 5 are differential latch-enable inputs for Channel B (LEB and LEB). They provide noise-immune latching: the comparator samples input state only when the differential pair crosses its threshold. This eliminates false triggering from ground bounce or EMI that could affect single-ended latch inputs.
Can MAX9693ESE operate at temperatures beyond -40°C to +85°C?
No, MAX9693ESE is specified and tested only for operation from -40°C to +85°C. Exceeding this range risks parametric shift (e.g., increased propagation delay, degraded VOS), latch timing failure, or permanent damage. For extended temperature applications, consult Maxim's military-grade variants or alternative qualified parts.
