MM54HC20MM74HC20

Dual 4-Input NAND Gate

General Description

These NAND 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 All de-

vices have high noise immunity and the ability to drive 10

LS-TTL loads The 54HC74HC logic family is functionally

as well as pin-out compatible with the standard 54LS74LS

logic family All inputs are protected from damage due to

static discharge by internal diode clamps to VCC and

ground
