4-Bit Magnitude Comparator

High–Performance Silicon–Gate CMOS

The MC74HC85 is identical in pinout and function to the LS85. This device is similar in function to the MM74C85 and L85, but has a different pinout. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This 4–Bit Magnitude Comparator compares two 4–bit nibbles and gives a high voltage level on either the A > Bout, A = Bout, or A Bin, A = Bin, and A

• Output Drive Capability: 10 LSTTL Loads

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2 to 6 V

• Low Input Current: 1 µA

• High Noise Immunity Characteristic of CMOS Devices

• In Compliance with the Requirements Defined by JEDEC Standard No. 7A

• Chip Complexity: 248 FETs or 62 Equivalent Gates
