1. General description

The 74LV14 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC14

and 74HCT14.

The 74LV14 provides six inverting buffers with Schmitt-trigger input. It is capable of transforming

slowly-changing input signals into sharply defined, jitter-free output signals.

The inputs switch at different points for positive and negative-going signals. The difference between

the positive voltage VT+ and the negative voltage VT- is defined as the input hysteresis voltage VH.

2. Features and benefits

• Wide supply voltage range from 1.0 V to 5.5 V

74LV14属于集成电路（IC） > 门和反相器。安世半导体(中国)有限公司制造生产的74LV14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。
