74VHCT04A集成電路（IC）的門反相器規(guī)格書PDF中文資料

74VHCT04A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(chǎn)的74VHCT04A門和反相器邏輯柵極和逆變器系列中的產(chǎn)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。

General Description

The VHCT04A is an advanced high speed CMOS Inverter fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output.

Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC = 0V. These circuits prevent device destruction due to mismatched supply and input/ output voltages. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup.

Features
