GENERAL DESCRIPTION
AD8564
8
9
The AD8564 is quad 7 ns comparator with separate input and
output supplies, thus enabling the input stage to be operated
from
卤
5 V dual supplies or a +5 V single supply while maintain-
ing 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 (鈥?0掳C to +85掳C)
temperature range. The quad AD8564 is available in the 16-
lead plastic DIP, narrow SO-16 surface mount, and 16-lead
TSSOP packages.
