DESCRIPTION

PIN CONNECTIONS (top view)

The M54/74HC85 is a high speed CMOS 4-BIT

MAGNITUDE COMPARATOR fabricated in silicon

gate C²MOS technology. It has the same high

speed performance of LSTTL combined with true

CMOS low power consumption. This comparator

compares two 4-bit words and provides a high volt-

age level on one ofthe A > B out, A =B out and A <B

out outputs. The comparing bit number is easily ex-

panded by cascading several devices as shown in

the typical application. All inputs are equipped with

protection circuits against static discharge and tran-

sient excess voltage.
