8-Input NOR/OR Gate

High–Performance Silicon–Gate CMOS

The MC74HC4078 is similar to the CD4078B metal–gate CMOS device.

The device inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LSTTL outputs.

• 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: 30 FETs or 7.5 Equivalent Gates
