MM74HC14集成電路（IC）的門反相器規(guī)格書PDF中文資料

MM74HC14屬于集成電路（IC）的門反相器。由安森美半導體公司制造生產的MM74HC14門和反相器邏輯柵極和逆變器系列中的產品對單個邏輯信號執(zhí)行基本邏輯運算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲信息，不會對提供給其輸入的信號立即做出響應。雖然早就被集成電路實施形式所取代，以用于實現(xiàn)復雜功能，但分立柵極仍可在僅需要非常簡單邏輯功能的情況下使用。

Features

■ Typical propagation delay: 13ns

■ Wide power supply range: 2V–6V

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

■ Low input current: 1μA maximum

■ Fanout of 10 LS-TTL loads

■ Typical hysteresis voltage: 0.9V at VCC = 4.5V

General Description

The MM74HC14 utilizes advanced silicon-gate CMOS

technology to achieve the low power dissipation and

high noise immunity of standard CMOS, as well as the

capability to drive 10 LS-TTL loads.

The 74HC logic family is functionally and pinout 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.
