Product Introduction

Overview

The AD8564ARZ, produced by Analog Devices Inc., is a quad 7 ns single-supply comparator. This device is designed to operate with either a 5 V single supply or ±5 V dual supplies, while maintaining CMOS- and TTL-compatible outputs. It is particularly suited for high-speed timing circuits, line receivers, and data communications due to its fast 7 ns propagation delay and independent analog and digital supplies, which provide excellent protection from supply pin interaction.
