The M74HC85 is an high speed CMOS 4-BIT MAGNITUDE COMPARATOR fabricated with silicon gate C2MOS technology.
The M74HC85 compares two 4-bit words and provides an high voltage level on one of the A>B out, A=B out and A<B out outputs. The comparing bit number is easily expanded by cascading several devices as shown in the typical application.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.
