CD4051-054

CD4051和CD4052是数字控制的模拟开关,具有低导通阻抗和极低的关断漏电流。它们可以通过4.5V至20V的数字信号幅度控制高达20V峰峰值(如果VDD-VSS为3V,则VDD-VEE可高达13V;对于VDD-VEE电平差异超过13V的情况,需要至少4.5V的VDD-VSS)。例如,如果VDD=+4.5V,VSS=0,VEE=-13.5V,则可以通过0至5V的数字输入控制从-13.5V至+4.5V的模拟信号。这些多路复用电路在整个VDD-VSS和VDD-VEE电源电压范围内消耗极低的静态功耗,与控制信号的逻辑状态无关。当禁止输入端出现逻辑“1”时,所有通道均关闭。CD4051是一款具有三个二进制控制输入A、B和C以及一个禁止输入的单8通道多路复用器。这三个二进制信号选择1个8通道打开,并将一个输入连接到输出。CD4052是一款具有两个二进制控制输入A和B以及一个禁止输入的差分4通道多路复用器。
