GENERAL DESCRIPTION
LATCH
The AD8561 is a single 7 ns comparator with separate input and
output sections. Separate supplies enable the input stage to be
operated from ±5 V dual supplies and +5 V single supplies.
Fast 7 ns propagation delay makes the AD8561 a good choice
for timing circuits and line receivers. Propagation delays for
rising and falling signals are closely matched and track over
temperature. This matched delay makes the AD8561 a good
choice for clock recovery, since the duty cycle of the output will
match the duty cycle of the input.
The AD8561 has the same pinout as the LT1016, with lower
supply current and a wider common-mode input range, which
includes the negative supply rail.
The AD8561 is specified over the industrial (–40°C to +85°C)
temperature range. The AD8561 is available in both the 8-lead
plastic DIP, 8-lead TSSOP or narrow SO-8 surface mount
packages.
