GENERAL DESCRIPTION

The AD8611/AD8612 are single and dual 4 ns comparators with latch function and complementary output. The latch is not functional if VCC is less than 4.3 V.

Fast 4 ns propagation delay makes the AD8611/AD8612 good choices for timing circuits and line receivers. Propagation delays for rising and falling signals are closely matched and tracked over temperature. This matched delay makes the AD8611/AD8612 good choices for clock recovery because the duty cycle of the

output matches the duty cycle of the input.
