General Description

The MM74HC02 NOR gates utilize advanced silicon-

gate CMOS technology to achieve operating speeds

similar to LS-TTL gates with the low power consumption

of standard CMOS integrated circuits. All gates have

buffered outputs, providing high noise immunity and the

ability to drive 10 LS-TTL loads. The 74HC logic family is

functionally as well as pin-out compatible with the stan-

dard 74LS logic family. All inputs are protected from

damage due to static discharge by internal diode clamps
