CD74HC03集成电路（IC）的门反相器规格书PDF中文资料

CD74HC03属于集成电路（IC）的门反相器。由德州仪器制造生产的CD74HC03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。

描述 Description

The ’HC03 and ’HCT03 logic gates utilize silicon gate CMOS

technology to achieve operating speeds similar to LSTTL

gates with the low power consumption of standard CMOS

integrated circuits. All devices have the ability to drive 10

LSTTL loads. The HCT logic family is functionally as well as

pin compatible with the standard LS logic family.

These open drain NAND gates can drive into resistive loads

to output voltages as high as 10V. Minimum values of RL

required versus load voltage are shown in Figure 2.
