These 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 54HC/74HC logic family is functionally as well as pinout compatible with the standard 54LS/74LS logic family.All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.
