74LVC32A中文资料Standard-logic数据手册Diodes规格书

描述 Description

The 74LVC32A provides four independent 2-input OR gates. The device is designed for operation with a power supply range of 1.65V to 3.6V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment. The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down.

简介

74LVC32A属于集成电路（IC）的门反相器。由制造生产的74LVC32A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。
