MC74VHCT86AD集成電路（IC）的門反相器規(guī)格書PDF中文資料

MC74VHCT86AD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MC74VHCT86AD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。

Quad 2?Input XOR Gate / CMOS Logic Level Shifter

with LSTTL–Compatible Inputs

The MC74VHCT86A is an advanced high speed CMOS 2–input Exclusive–OR gate fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL 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 compatible with TTL–type input thresholds and the output has a full 5V 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 3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic while operating at the high–voltage power supply.

The MC74VHCT86A input structure provides protection when voltages up to 7V are applied, regardless of the supply voltage. This allows it to be used to interface 5V circuits to 3V 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.
