GENERAL DESCRIPTION
The AD8611/AD8612 are single and dual 4 ns comparators
with latch function and complementary output. The latch is not
functional if 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.

The AD8611 has the same pinout as the LT1016 and LT1394,
with lower supply current and a wider common-mode input
range, which includes the negative supply rail.
The AD8611/AD8612 are specified over the industrial temper-
ature range (−40°C to +85°C). The AD8611 is available in both
8-lead MSOP and narrow 8-lead SOIC surface-mount packages.
The AD8612 is available in a 14-lead TSSOP surface-mount
package.
