Analog Devices Inc./Maxim Integrated MAX9600EUP+T

Overview

MAX9600EUP+T from Maxim Integrated is a dual-channel ultra-high-speed ECL-output comparator with 500ps propagation delay, 10ps channel skew, and -2.2V to +3V input common-mode range under ±5.2V/5V supplies. It features latch-enable (LE_, LE_) and current-controlled hysteresis (HYS_) for track-hold/sampling operation and noise immunity in high-fidelity pulse tracking applications such as VLSI ATE and logic analyzer front ends.

For engineers reviewing the MAX9600EUP+T datasheet, MAX9600EUP+T pinout, MAX9600EUP+T application, or MAX9600EUP+T equivalent, this page delivers verified electrical specs, TSSOP-20 package mapping, latch timing constraints, ECL output drive capability into 50Ω, and validated alternative comparators for high-speed sampling and threshold detection systems.

Technical Context

The MAX9600EUP+T employs a bipolar process with 558 transistors to achieve sub-nanosecond timing precision. Its differential input stage supports common-mode voltages from (VEE + 3V) to (VCC − 2V), delivering 70dB CMRR and ±9mV input offset voltage over temperature.

It implements complementary latch-enable control enabling deterministic track-hold mode, with setup/hold times of 250ps/300ps and latch-to-output delay of 200ps. Hysteresis is set via external RHYS_ (10kΩ–35kΩ) to GND, yielding 5–60mV input-referred hysteresis without affecting propagation delay dispersion (≤30ps).

Key Specifications

Pinout & Package

MAX9600EUP+T is housed in a 20-pin TSSOP package (4.4mm body width) with exposed pad for thermal enhancement. Pin 1 is QA (Channel A output); pin 2 is QA̅ (Channel A complementary output); pins 3 and 18 are GND (output ground); pins 6 and 15 are VEE (−5.2V supply); pins 7 and 14 are VCC (+5V supply); pins 4 and 17 are LEA/LEB (latch-enable inputs); pins 5 and 16 are LEA̅/LEB̅ (complementary latch-enable inputs); pins 8 and 13 are HYSA/HYSB (hysteresis inputs); pins 9–12 are INA−, INA+, INB+, INB− (differential inputs).

FAQ

What is the maximum operating frequency supported by the MAX9600EUP+T?

The MAX9600EUP+T supports a 4Gbps tracking frequency with 500ps propagation delay and ≤30ps propagation delay dispersion. This allows reliable operation with input pulse widths down to 250ps and toggle rates up to 4Gbps under specified conditions (VCC = 5V, VEE = −5.2V, RL = 50Ω to −2V, CL = 5pF). The device maintains timing integrity across input overdrive, slew rate, and common-mode voltage variations.

How do I configure the hysteresis function on the MAX9600EUP+T?

To configure hysteresis on the MAX9600EUP+T, connect an external resistor (RHYS_) between each HYS_ pin (pins 8 and 13) and GND. Values from 10kΩ to 35kΩ yield input-referred hysteresis from 60mV down to 5mV, as shown in the "Hysteresis vs. RHYS to GND" graph. Leaving HYS_ open sets hysteresis to zero. Do not tie HYS_ to VCC unless zero hysteresis is required - MAX9600EUP+T does not source current from this pin.

Can the MAX9600EUP+T operate with non-standard supply voltages?

Yes, the MAX9600EUP+T operates with two validated supply configurations: standard (VCC = +5V, VEE = −5.2V) and shifted (VCC = +6V, VEE = −4.2V). Absolute maximum ratings allow VCC up to +6.3V and VEE down to −6V, but DC electrical characteristics (e.g., input range, output swing) are only guaranteed within the specified ranges. Input common-mode range adjusts accordingly: −1.2V to +4V with +6V/−4.2V supplies.

What are the layout requirements for stable operation of the MAX9600EUP+T?

Stable operation of the MAX9600EUP+T requires strict RF layout: use a solid low-inductance ground plane; place 0.01µF ceramic decoupling capacitors within 2mm of each VCC and VEE pin; route differential inputs and outputs as controlled-impedance microstrips; terminate all outputs in 50Ω to VT = −2V; minimize vias and trace length; and match electrical lengths of IN+/IN− and Q/Q̅ pairs to limit skew. Avoid stubs or discontinuities that induce parasitic feedback.

Is the MAX9600EUP+T pin-compatible with the MAX9601EUP+T?

Yes, the MAX9600EUP+T and MAX9601EUP+T share identical 20-pin TSSOP packaging, pin numbering, and functional pin assignments (including LE_, HYS_, and differential I/O). The only difference is output type: MAX9600EUP+T provides ECL outputs referenced to GND, while MAX9601EUP+T provides PECL outputs referenced to VCCO_. No PCB changes are required when substituting, but VCCO_ must be supplied externally for MAX9601EUP+T operation.
