ANALOG DEVICES AD8611ARMZ-R2

AD8611 is a single 4ns comparator with latch function and complementary output. The latch is not functional if VCC is less than 4.3V. Fast 4ns propagation delay makes the AD8611 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 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. Typical application includes high speed timing, clock recovery and clock distribution, line receivers, digital communications, phase detectors, high speed sampling, read channel detection, PCMCIA cards, zero-crossing detector and high speed analogue-to-digital converter(ADC).
