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 theA > Bout, A =Bout 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.
