TC74HC85AP,TC74HC85AF,TC74HC85AFN 4-Bit Magnitude Comparator
The TC74HC85A is a high speed CMOS 4 BIT MAGNITUDE COMPARATOR fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The TC74HC85A compares tow 4-bit words applied to inputs A0-A3 and B0-B3, and provides a high voltage level on one of three outputs: A > B, A < B, or A = B.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
