AD8561A

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.
