3 Description

The SNx4AHC14 devices contain six independent

inverters. These devices perform the boolean function

Y = A.

Each circuit functions as an independent inverter, but,

because of the Schmitt-Trigger action, the inverters

have different input threshold levels for positive-going

(VT+) and negative-going (VT–) signals.

SN74AHC14DR属于集成电路（IC） > 门和反相器。美国德州仪器公司制造生产的SN74AHC14DR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。
