GENERAL DESCRIPTION
The ADCMP563/ADCMP564 are high speed comparators
fabricated on Analog Devices’ proprietary XFCB process. The
devices feature a 700 ps propagation delay with less than 75 ps
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
−2.0 V to +3.0 V. Outputs are complementary digital signals

However, no responsibility is assumed by Analog Devices for its use, nor for any
infringements of patents or other rights of third parties that may result from its use.
Specifications subject to change without notice. No license is granted by implication
or otherwise under any patent or patent rights of Analog Devices. Trademarks and

Dual, High Speed ECL Comparators
that are 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 Ω to −2 V. 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.
The ADCMP563/ADCMP564 are specified over the industrial
temperature range (−40°C to +85°C).
