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
Features
