Overview
The CD4051BE is a CMOS single 8-channel analog multiplexer/demultiplexer produced by Texas Instruments. It is part of the CD405xB series, which includes digitally-controlled analog switches with low ON impedance and very low OFF leakage current. These multiplexers are designed to handle a wide range of digital and analog signal levels, making them versatile for various applications. The device operates with extremely low quiescent power dissipation across the full supply-voltage ranges, independent of the logic state of the control signals.
