数字集成电路输出与输入之间的关系并不是放大关系,而是一种逻辑关系。输入条件满足时,输出高电平或低电平(只有这两种电平)。对数字集成电路进行检测,就是检测其输入引脚与输出引脚之间逻辑关系是否存在。由于数字集成电路种类太多,完成的逻辑功能又多种多样,逐项检测其指标高 Digital IC output and the relationship between the input is not to enlarge the relationship, but a logical relationship. When the input condition is met, the output is high level or low level (only two levels). The digital integrated circuit to detect, is to detect the logic of the input pin and the output pin exists. As the type of digital integrated circuits too much to complete a variety of logic functions, one by one to detect the high index
