Low-Voltage CMOS Quad 2-Input OR Gate

With 5 V−Tolerant Inputs

The MC74LCX32 is a high performance, quad 2−input OR gate operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX32 inputs to be safely driven from 5.0 V devices.

Current drive capability is 24 mA at the outputs.

MC74LCX32D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MC74LCX32D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。
