The device propagation delay with a wide variety of signals in the common- features 250 ps propagation delay with less than 35 ps overdrive mode range from 2.0 V to +3.0 V. Outputs are complementary dispersion. Overdrive dispersion, a particularly important digital signals fully compatible with PECL 10 K and 10 KH characteristic of high speed comparators, is a measure of the logic families. The outputs provide sufficient drive current to difference in propagation delay under differing overdrive directly drive transmission lines terminated in 50 to V 2 V. DD conditions. A latch input is included, which permits tracking, track-and- hold, or sample-and-hold modes of operation. The ADCMP567 is available in a 32-lead LFCSP package. Rev.
