Overview
The HCF4051BM1, produced by STMicroelectronics, is a single 8-channel analog multiplexer/demultiplexer. This device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology and is available in SO-16 and PDIP-16 packages. It operates as a digitally controlled analog switch with low ON impedance and very low OFF leakage current. The HCF4051BM1 is designed to dissipate extremely low quiescent power over the full supply voltage range, independent of the logic state of the control signals.
