MM74HC20N/A+ 技术参数

January 1988

MM54HC20/MM74HC20

Dual 4-Input NAND Gate

General Description

Features

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 54HC/74HC logic family is functionally

as well as pin-out compatible with the standard 54LS/74LS

logic family. All inputs are protected from damage due to

Typical propagation delay: 8 ns

Wide power supply range: 2–6V

Low quiescent current: 20 mA maximum (74HC Series)

Low input current: 1 mA maximum

Fanout of 10 LS-TTL loads

static discharge by internal diode clamps to

ground.
