Overview
The HCF4051BEY, 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 PDIP-16 and SO-16 packages. It operates as a digitally controlled analog switch with low ON impedance and very low OFF leakage current. The HCF4051BEY is designed to dissipate extremely low quiescent power over a wide range of supply voltages, making it highly efficient in various applications.
