The AD8564 is 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.
All four comparators have similar propagation delays. The propagation delay for rising and falling signals is similar, and tracks over temperature and voltage. These characteristics make the AD8564 a good choice for high speed timing and data communications circuits. For a similar dual comparator with a latch function, please see the AD8598 data sheet. For a similar single comparator with latch function, please see the AD8561 data sheet.
The AD8564 is specified over the industrial (40°C to +85°C) temperature range. The quad AD8564 is available in the 16-lead plastic DIP, narrow SO-16 surface mount, and 16-lead TSSOP packages.
