Quad 2-Input Exclusive

NOR Gate

High–Performance Silicon–Gate CMOS

The MC74HC7266A is identical in pinout to the LS266 and the HC266.

The HC7266 has standard CMOS outputs instead of open–drain outputs.

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: 56 FETs or 14 Equivalent Gates
