MC74VHCT08A集成电路（IC）的门反相器规格书PDF中文资料

MC74VHCT08A属于集成电路（IC）的门反相器。由安森美半导体制造生产的MC74VHCT08A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。

The MC74VHCT08A is an advanced high speed CMOS 2−input

AND 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 VHCT inputs are compatible with TTL levels. This device can

be used as a level converter for interfacing 3.3 V to 5.0 V, because it

has full 5.0 V CMOS level output swings.

The VHCT08A input structures provide protection when voltages

between 0 V and 5.5 V are applied, regardless of the supply voltage.

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.

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.
