描述 Description

The MC74VHC1GT04 is a singleinverting buffer fabricated in silicon gate CMOS technology. It achieves high speed operation while maintaining CMOS low power dissipation. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The device input is has low input threshold and the output has a full 5V CMOS level output swing. The input protection circuitry on this device is overvoltage tolerant, allowing the device to be used as a logic-level translator. The MC74VHC1GT04 input structure provides protection when voltages up to 7V are applied, regardless of the supply voltage, allowing the the part to be used to interface 1.8/3.3V 3/5V circuits . The output structures also provide protection when VCC = 0V.These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.

簡介

MC74VHC1GT04屬于集成電路（IC）的門反相器。由制造生產(chǎn)的MC74VHC1GT04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(yīng)。雖然早就被集成電路實施形式所取代，以用于實現(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。
