AD8564ARUZ-REEL

AD8564 is a quad 7ns comparator with separate input and output supplies, thus enabling the input stage to be operated from ±5V dual supplies or a 5V single supply while maintaining a CMOS-/TTL-compatible output. Independent analogue 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. This characteristic makes the AD8564 a good choice for high speed timing and data communications circuits. Applications include high speed timing, line receivers, data communications, high speed V-to-F converters, battery operated instrumentation, high speed sampling systems, window comparators, PCMCIA cards, upgrade for MAX901 designs.
