The ADCMP551/ADCMP552/ADCMP553 are single-supply, high speed comparators fabricated on Analog Devices, Inc., proprietary XFCB process. The devices feature a 500 ps propagation delay with less than 125 ps overdrive dispersion. Overdrive 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 ADCMP552. A differential input stage permits consistent propagation delay with a common-mode range from −0.2 V to VCCI − 2.0 V. Outputs are complementary digital signals and are fully compatible with PECL and 3.3 V LVPECL logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 Ω to VCCO − 2 V. A latch input is included and 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. The ADCMP551/ADCMP552/ADCMP553 are specified over the −40°C to +85°C industrial temperature range. The ADCMP551 is available in a 16-lead QSOP package; the ADCMP552 is available in a 20-lead QSOP package; and the ADCMP553 is available in an 8-lead MSOP package. 04722-001 NONINVERTING INPUT INVERTING INPUT LATCH ENABLE INPUT Q OUTPUT LATCH ENABLE INPUT Q OUTPUT ADCMP551/ ADCMP552/ ADCMP553 *ADCMP552 ONLY HYS*
