The is a dual high speed ECL Comparator fabricated on proprietary XFCB process. The device features a 700ps propagation delay with less than 75ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of high speed comparators. A separate programmable hysteresis pin is available on the ADCMP564. A differential input stage permits consistent propagation delay with a wide variety of signals in the common-mode range from -2 to 3V. Outputs are complementary digital signals that are fully compatible with ECL 10K and 10KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50R to -2V. A latch input, which is included, permits tracking, track-and-hold or sample-and-hold modes of operation. The latch input pins contain internal pull-ups that set the latch in tracking mode when left open.
