MC10H166

5−Bit Magnitude

Comparator

Description

The MC10H166 is a 5−Bit Magnitude Comparator and is a

functional/ pinout duplication of the standard MECL 10K

™ part with

100% improvement in propagation delay and no increase in

power−supply current.

The MC10H166 is a high−speed expandable 5−bit comparator for

comparing the magnitude of two binary words. Two outputs are

provided: A < B and A > B. The A = B function can be obtained by

wire−ORing these outputs (a low level indicates A = B) or by

wire−NORing the outputs (a high level indicates A = B). A high level

on the enable function forces both outputs low.
