MC74VHC14集成電路（IC）的門反相器規(guī)格書PDF中文資料

MC74VHC14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MC74VHC14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單邏輯功能的情況下使用。

The MC74VHC14 is an advanced high speed CMOS Schmitt inverter fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.

Pin configuration and function are the same as the MC74VHC04 but the inputs have hysteresis and, with its Schmitt trigger function, the VHC14 can be used as a line receiver which will receive slow input signals.

The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.
