74VHC08集成電路（IC）的門反相器規(guī)格書(shū)PDF中文資料

74VHC08屬于集成電路（IC）的門反相器。由安森美半導(dǎo)體公司制造生產(chǎn)的74VHC08門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對(duì)單個(gè)邏輯信號(hào)執(zhí)行基本邏輯運(yùn)算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲(chǔ)信息，不會(huì)對(duì)提供給其輸入的信號(hào)立即做出響應(yīng)。雖然早就被集成電路實(shí)施形式所取代，以用于實(shí)現(xiàn)復(fù)雜功能，但分立柵極仍可在僅需要非常簡(jiǎn)單邏輯功能的情況下使用。

General Description

The VHC08 is an advanced high speed CMOS 2 Input AND Gate

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 4 stages including buffer output,

which provide high noise immunity and stable output. An input

protection circuit insures that 0 V to 7 V can be applied to the input

pins without regard to the supply voltage. This device can be used to

interface 5 V to 3 V systems and two supply systems such as battery

backup. This circuit prevents device destruction due to mismatched

supply and input voltages.
