MC74VHCT00A数据手册集成电路（IC）的门反相器规格书PDF

描述 Description

The MC74VHCT00A is an advanced high speed CMOS 2-Input NAND gate fabricated with 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 compatible with TTL-type input thresholds and the output has a full 5 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 MC74VHCT00A input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHCT00A 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.

简介

MC74VHCT00A属于集成电路（IC）的门反相器。由制造生产的MC74VHCT00A门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。
