CMOS逻辑IC多路复用器是一种从多个输入信号中选择一个输出信号的器件。由于输出为CMOS结构,因此具有驱动能力,并且不容易受到后级负载的影响。它处理数字信号,信号传输为单向传输(输入 → 输出)。 而总线开关多路复用器也可以从多个输入信号中输出一个信号。它较易受到噪音的影响,主要用于信号阻断和切换。它可以处理数字信号和模拟信号。此外,信号可以双向传输。
CMOS逻辑IC多路复用器
以TC74HC257(4路2通道多路复用器)为例。
通过SELECT端子的输入信号电平,选择从A端子输出的信号或从B端子输出的信号,并从Y端子进行输出。
总线开关多路复用器
以TC7SB3157(1路2通道多路复用器)为例。
通过S端子(SELECT端子)的输入信号电平,选择A-B1路径或A-B2路径。信号可以双向传输。
