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.

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 single comparator with
latch function, refer to the AD8561 data sheet.
The AD8564 is specified over the industrial temperature range
(−40°C to +125°C). The quad AD8564 is available in the 16-lead
TSSOP, 16-lead narrow body SOIC, and 16-lead plastic DIP
packages.
