The CD4051B, CD4052B, and CD4053B analog multiplexers are digitally-controlled analog switches having low ON impedance and very low OFF leakage current. Control of analog signals up to 20VP-P can be achieved by digital signal amplitudes of 4.5V to 20V (if VDD-VSS = 3V, a VDD-VEE of up to 13V can be controlled; for VDD-VDD level differences above 13V, a VDD-VDD of at least 4.5V is required). For example, if VDD = +4.5V, VDD = 0V, and VDD = -13.5V, analog signals from -13.5V to +4.5V can be controlled by digital inputs of 0V to 5V. These multiplexer circuits dissipate extremely low quiescent power over the full VDD-VDD and VDD-VDD supply-voltage ranges, independent of the logic state of the control signals. When a logic “1” is present at the inhibit input terminal, all channels are off.

单路8选1模拟开关和多路复用器;

GC74HC4051、4052、4053 是一组用高速CMOS 工艺设计制作的高性能双向模拟开关，这些模拟开关具有很低的导通电阻和很小的关断漏电流。这些模拟开关的关断和切换由外部数字信号控制，芯片内部含有逻辑电平转换器，因此，输入控制电平和74HC 系列数字电路一致，2V 到6V 的数字电平均可对模拟开关实现控制。模拟开关的衬底和外部输入的电平VEE 相连，VEE 的电平可在0V 到-7V 的范围内选择，因此，可实现对负向模拟信号的传送。被传送模拟信号的最大峰-峰值可达+/-5V。GC74HC405X 系列模拟开关的典型导通电阻小于50 欧姆，允许通过的模拟信号频率可达200MHz。因此，特别适合于传送和切换高频信号、视频信号。
