The MM74HC02 is a Quad 2-Input NOR Gate 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 standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
Typical propagation delay: 8 ns
Wide power supply range: 2-6V
Low quiescent supply current: 20 µA maximum (74HC Series)
