GENERAL DESCRIPTION
The AD8611/AD8612 are single and dual 4 ns comparators The AD8611 has the same pinout as the LT1016 and LT1394, with latch function and complementary output. The latch is not with lower supply current and a wider common-mode input functional if VCC is less than 4.3 V. range, which includes the negative supply rail. Fast 4 ns propagation delay makes the AD8611/AD8612 good The AD8611/AD8612 are specified over the industrial temper- choices for timing circuits and line receivers. Propagation delays ature range (−40°C to +85°C). The AD8611 is available in both for rising and fal ing signals are closely matched and tracked over 8-lead MSOP and narrow 8-lead SOIC surface-mount packages. temperature. This matched delay makes the AD8611/AD8612 The AD8612 is available in a 14-lead TSSOP surface-mount good choices for clock recovery because the duty cycle of the package. output matches the duty cycle of the input.
