SN74LS38NSR集成电路（IC）的门反相器规格书PDF中文资料

SN74LS38NSR属于集成电路（IC）的门反相器。由德州仪器制造生产的SN74LS38NSR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。

description

These devices contain four independent 2-input NAND

buffer gates with open-collector outputs. The open-

collector outputs require pull-up resistors to perform

correctly. They may be connected to other open-

collector outputs to implement active-low wired-OR or

active-high wired-AND functions. Open-collector

devices are often used to generate high VOH levels.

The SN5438, SN54LS38, and SN54S38 are

characterized for operation over the full military

temperature range of ~55°C to 125°C. The SN7438,

SN74LS38, and SN74S38 are characterized for opera-

tion from 0°C to 70°C.
