Analog Devices Inc./Maxim Integrated MAX964ESE+T

Overview

The MAX964ESE+T from Maxim Integrated is a quad ultra-high-speed comparator with internal hysteresis, optimized for single +3V or +5V operation. It features 4.5ns propagation delay (5mV overdrive), ±3.5mV input-referred hysteresis, 5mA supply current per comparator, and shutdown mode consuming only 270μA per comparator - used in GPS receivers, high-speed sampling circuits, and line receivers.

For engineers reviewing the MAX964ESE+T datasheet, MAX964ESE+T pinout, MAX964ESE+T application, or MAX964ESE+T equivalent, key selection criteria include propagation delay skew (<0.3ns between channels), rail-to-rail input range extending 100mV beyond rails, TTL/CMOS-compatible outputs, and 16-pin narrow SO package compatibility with space-constrained PCB layouts.

Technical Context

The MAX964ESE+T implements a current-driven output stage enabling fast slew rates while maintaining low static power; its internal 3.5mV hysteresis eliminates need for external feedback resistors and prevents oscillation near trip points. Input protection includes dual 200Ω series resistors and front-to-back diode clamps limiting differential voltage to ≤2.1V.

It supports shutdown via logic-high SHDN pin, forcing outputs into high-impedance state and reducing supply current to 270μA per comparator. The device operates across -40°C to +85°C and accepts supply voltages from +2.7V to +5.5V, with input common-mode range from -0.1V to VCC + 0.1V.

FAQ

What is the maximum operating supply voltage for the MAX964ESE+T?

The MAX964ESE+T supports a maximum supply voltage of +5.5V relative to GND, with absolute maximum rating of -0.3V to +6V on VCC. Operation above +5.5V risks permanent damage. The device is fully specified from +2.7V to +5.5V, ensuring reliable performance across Li-ion battery discharge profiles and regulated 3.3V/5V rails. This range makes the MAX964ESE+T compatible with both modern low-voltage SoCs and legacy 5V logic systems.

Does the MAX964ESE+T include internal hysteresis, and what is its value?

Yes, the MAX964ESE+T includes fixed internal hysteresis of 3.5mV (input-referred), eliminating the need for external positive-feedback resistors. This hysteresis creates distinct upper and lower trip points, preventing output oscillation during slow-moving or noisy input transitions. The 3.5mV value is tightly controlled across temperature and supply voltage, ensuring consistent noise immunity in GPS receivers and high-speed sampling circuits where the MAX964ESE+T is commonly deployed.

How does the shutdown mode function on the MAX964ESE+T?

The MAX964ESE+T enters shutdown mode when the SHDN pin is driven logic-high, reducing supply current per comparator to 270μA and placing all four outputs (QA–QD) in high-impedance state. Normal operation resumes within 250ns after SHDN is pulled low. During shutdown, internal biasing is disabled but input protection circuitry remains active. This feature is essential for power-gating in portable instruments using the MAX964ESE+T for intermittent threshold monitoring.

What is the input common-mode voltage range specification for the MAX964ESE+T?

The MAX964ESE+T features a Beyond-the-Rails™ input common-mode range of -0.1V to VCC + 0.1V, meaning either input can safely operate 100mV below GND or 100mV above VCC without damage or invalid output states. This capability enables direct interfacing with sensors whose outputs swing beyond supply rails - such as piezoelectric transducers or thermocouples - without external level-shifting circuitry, a key advantage in compact GPS receiver and portable test equipment designs using the MAX964ESE+T.

Can the MAX964ESE+T drive standard TTL or CMOS logic loads directly?

Yes, the MAX964ESE+T provides TTL/CMOS-compatible push-pull outputs capable of sourcing or sinking 4mA while maintaining VOH ≥ VCC – 0.52V and VOL ≤ 0.52V. This meets standard 3.3V and 5V logic thresholds without external pull-up resistors. Its 2.3ns rise/fall time and low output capacitance (4pF) ensure clean signal integrity when driving FPGA I/O banks or microcontroller GPIO pins - a verified design requirement in applications like high-speed line receivers and zero-crossing detectors where the MAX964ESE+T is routinely applied.
