The MC74VHC1G32 / MC74VHC1GT32 is a single 2−input OR

Gate in tiny footprint packages. The MC74VHC1G32 has

CMOS−level input thresholds while the MC74VHC1GT32 has

TTL−level thresholds.

The input structures provide protection when voltages up to 5.5 V

are applied, regardless of the supply voltage. This allows the device to

be used to interface 5 V circuits to 3 V circuits. Some output structures

also provide protection when VCC = 0 V and when the output voltage

exceeds VCC. These input and output structures help prevent device

destruction caused by supply voltage − input/output voltage mismatch,

battery backup, hot insertion, etc.

MC74VHC1G32属于集成电路（IC） > 门和反相器。安森美半导体公司制造生产的MC74VHC1G32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。
