74LCX00中文资料Low voltage CMOS QUAD 2-Input NAND gate with 5V tolerant inputs数据手册ST规格书

描述 Description

The 74LCX00 device is a low-voltage CMOS quad dual input NAND gate manufactured with sub-micron silicon gate and double layer metal wiring C2MOS technology. It is ideal for low-power and high-speed 3.3 V applications and can be interfaced to a 5 V signal environment for inputs.
It has the same speed performance at 3.3 V as the 5 V AC/ACT family, combined with lower power consumption.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2 kV ESD immunity and transient excess voltage.

简介

74LCX00属于集成电路（IC）的门反相器。由制造生产的74LCX00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。
