MC74VHC1G14集成电路（IC）的门反相器规格书PDF中文资料

MC74VHC1G14属于集成电路（IC）的门反相器。由安森美半导体公司制造生产的MC74VHC1G14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。

Single Schmitt-Trigger Inverter

The MC74VHC1G14 / MC74VHC1GT14 is a single Schmitt−Trigger Inverter in tiny footprint packages. The MC74VHC1G14 has CMOS−level input thresholds while the MC74VHC1GT14 has TTL−level input thresholds.

The internal circuit is composed of three stages, including a buffered output which provides high noise immunity and stable output.

The input structures provide protection when voltages up to 5.5 V are applied, regardless of the supply voltage. This allows the device to be used to interface 5 V circuits to 3 V circuits. The output structures also provide protection when VCC = 0 V and when the output voltage exceeds VCC. These input and output structures help prevent device destruction caused by supply voltage − input/output voltage mismatch, battery backup, hot insertion, etc.
