M74HC85 4-BIT MAGNITUDE COMPARATOR

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 voltage level on one of the A > B ou.
