SEMICONDUCTOR TECHNICAL DATA
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.
