CD4051B

具有逻辑电平转换功能的 CMOS 单路 8 通道模拟多路复用器/多路解复用器

The CD405xB analog multiplexers and demuliplexers are digitally-controlled analog switches having low ON impedance and very low OFF leakage current. These multiplexer circuits dissipate extremely low quiescent power over the full VDD – VSS and VDD – VEE supply-voltage ranges, independent of the logic state of the control signals.
