前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件代替GB/T3431.2—1986《半导体集成电路文字符号引出端功能符号》，与GB/T3431.2—

1986相比，除结构调整和编辑性改动外，主要技术变化如下：

——增加了“范围”（见第1章）；

——删除了“常用数字集成电路电源端、接地端符号”和“常用的数字集成电路输入端、输出端符

号”（见1986年版的2.1和2.2）；

——增加了“常用的电源端、接地端符号”（见5.1）；

——将“常用的数字集成电路：门电路、触发器、运算器、寄存器、编码器、数据选择器、译码器、计数

器、存储器的输入端、输出端符号”，合并为“常用的数字集成电路输入端、输出端符号”（见

5.2，1986年版的2.2）；

——将“常用的模拟集成电路：运算放大器、集成稳压器输入端、输出端符号”，合并为“常用的模拟

集成电路输入端、输出端符号”（见5.3，1986年版的3.2）；

——删除了较多专用引出端符号（见1986年版的2.2、3.2）；

——增加了一些通用的引出端符号（见5.2~5.5）。

半导体集成电路文字符号

引出端功能符号

1范围

本文件规定了半导体集成电路（以下简称“器件”）的引出端功能的文字符号。

本文件适用于半导体集成电路产品引出端的识别。

2规范性引用文件

本文件没有规范性引用文件。

3术语和定义

本文件没有需要界定的术语和定义。

4引出端功能符号的组成

器件的引出端功能符号一般由基本符号、下标符号和前缀符号三部分组成。

a）基本符号：基本符号一般为一个或几个字母，可用国际惯用字母或缩写字母表示引出端的功

能或作用。

示例1：电源端V，接地端GND。

当在字母上方标“—”或在字母后加“#”时，表示低电平（或脉冲下降沿）有效。

b）下标符号：下标符号一般为一个或几个字母或阿拉伯数字。字母表示引出端的功能或作用，

阿拉伯数字表示同一功能引出端的序号。

示例2：数据输入端DS，第1位编码输入端IN1。

c）前缀符号：前缀符号一般为一个阿拉伯数字，表示同一器件中相同功能的单元。

示例3：双D触发器的第1触发器的数据输入端1D。

5常用引出端功能符号

5.1常用的电源端、接地端符号

常用的电源端、接地端符号见表1。
