The AD96685 and AD96687 are ultrafast voltage comparators. The AD96685 is a single comparator with 2.5 ns propagation delay; the AD96687 is an equally fast dual comparator. Both devices feature 50 ps propagation delay dispersion which is a particularly important characteristic of high-speed comparators. It is a measure of the difference in propagation delay under differing overdrive conditions. A fast, high precision differential input stage permits consistent propagation delay with a wide variety of signals in the commonmode range from 2.5 V to +5 V. Outputs are complementary digital signals fully compatible with ECL 10 K and 10 KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 to 2 V. A level sensitive latch input which permits tracking, track-hold, or sample-hold modes of operation is included. The AD96685 is available in industrial 25C to +85C range in 16-pin SOIC.
