MM74HC32MTC集成电路（IC）的门反相器规格书PDF中文资料

General Description

The MM74HC32 OR 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 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

Features

■ Typical propagation delay: 10ns

■ Wide power supply range: 2V–6V

■ Low quiescent current: 20µA maximum (74HC Series)

■ Low input current: 1µA maximum

■ Fanout of 10 LS-TTL loads
