MM54HC20中文资料Dual 4-Input NAND Gate数据手册TI规格书

描述 Description

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 devices 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 static discharge by internal diode clamps to VCC and ground.

特性 Features

■ Typical propagation delay: 8 ns
■ Wide power supply range: 2–6V
■ Low quiescent current: 20 μA maximum (74HC Series)
■ Low input current: 1 μA maximum
■ Fanout of 10 LS-TTL loads
