GENERAL DESCRIPTION
The AD8564 is a quad 7 ns comparator with separate input and output supplies, thus enabling the input stage to be operated from ±5 V dual supplies or a 5 V single supply while maintaining a CMOS-/TTL-compatible output.
Fast 7 ns propagation delay makes the AD8564 a good choice for timing circuits and line receivers. Independent analog and digital supplies provide excellent protection from supply pin interaction. The AD8564 is pin compatible with the MAX901 and has lower supply currents.
