The AD8561 is a single 7 ns comparator with separate input andoutput sections. Separate supplies enable the input stage to beoperated from ±5 V dual supplies and +5 V single supplies.Fast 7 ns propagation delay makes the AD8561 a good choicefor timing circuits and line receivers. Propagation delays forrising and falling signals are closely matched and track overtemperature. This matched delay makes the AD8561 a goodchoice for clock recovery, since the duty cycle of the output willmatch the duty cycle of the input.The AD8561 has the same pinout as the LT1016, with lowersupply current and a wider common-mode input range, whichincludes the negative supply rail.The AD8561 is specified over the industrial (–40°C to +85°C)temperature range. The AD8561 is available in both the 8-leadplastic DIP, 8-lead TSSOP or narrow SO-8 surface mountpackages.Applications High speed timing Clock recovery and clock distribution Line receivers Digital communications Phase detectors High speed sampling Read channel detection  PCMCIA cards Upgrade for LT1016 designs
