Overview
The AD8564ARUZ-REEL, produced by Analog Devices Inc., is a quad 7 ns comparator designed for high-speed applications. This component features separate input and output supplies, allowing the input stage to operate from ±5 V dual supplies or a single 5 V supply, while maintaining CMOS-/TTL-compatible outputs. This flexibility and high speed make the AD8564 an excellent choice for timing circuits, line receivers, and data communications circuits.
