Overview

The MAX999EUK+T is a high-speed, single-supply comparator featuring a 7ns propagation delay and a low 5mA supply current. It is designed for low-voltage systems, operating from 2.7V to 5.5V, and includes beyond-the-rails input capability for versatility in signal processing.

Why Choose This Part

The part offers a significant speed-to-power advantage, consuming only 5mA while achieving sub-10ns propagation delays. Its integrated 3.5mV hysteresis ensures clean output transitions even with slow-moving or noisy input signals, reducing the need for external components.

Applications

High-Speed Line Receivers
Used to convert fast-changing analog signals into clean TTL/CMOS digital outputs for data communication.
Zero-Crossing Detectors
Leverages the 3.5mV internal hysteresis to provide stable switching in timing applications without oscillation.
Threshold Detectors
Utilizes the beyond-the-rails input range to monitor signals that approach or slightly exceed the supply rails.
Window Comparators
Appropriate for high-speed fault detection circuits where fast response time is critical for system protection.

Getting Started

When designing with the MAX999EUK+T, place a 0.1uF ceramic bypass capacitor as close to the VCC pin as possible to handle high-speed switching transients. Ensure the output load is minimized to maintain the 7ns propagation delay, and keep input traces short to avoid parasitic oscillation.
