SN74LS19A中文资料具有施密特触发输入的 6 通道、4.75V 至 5.25V 双极反相器数据手册TI规格书

描述 Description

Each circuit functions as a NAND gate or inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and for negative-going (VT-) signals. The hysteresis or backlash, which is the difference between the two threshold levels (VT+ - VT-), is typically 800 millivolts. These circuits are temperature-compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.  

特性 Features

• Functionally and Mechanically Identical to 'LS13, 'LS14, and 'LS132, Respectively
• Improved Line-Receiving Characteristics
• P-N-P Inputs Reduce System Loading
• Excellent Noise Immunity with Typical Hysteresis of 0.8 V

简介

SN74LS19A属于集成电路（IC）的门反相器。由TI制造生产的SN74LS19A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。
