描述 Description

The MC74VHC1GT02 is a single gate 2?input NOR fabricated with silicon gate CMOS technology. The internal circuit is composed of multiple stages, including a buffer output which provides high noise immunity and stable output.The device input is compatible with TTL?type input thresholds and the output has a full 5.0 V CMOS level output swing. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic?level translator from 3.0 V CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V CMOS Logic while operating at the high?voltage power supply.The MC74VHC1GT02 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHC1GT02 to be used to interface 5 V circuits to 3 V circuits. The output structures also provide protection when VCC = 0 V.These input and output structures help prevent device destruction caused by supply voltage ? input/output voltage mismatch, battery backup, hot insertion, etc.

簡介

MC74VHC1GT02屬于集成電路（IC）的門反相器。由制造生產(chǎn)的MC74VHC1GT02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。
