Overview
The MC14051BDG, produced by onsemi, is a digitally-controlled analog multiplexer/demultiplexer. This device effectively implements an 8-channel single-pole single-throw (SP8T) solid-state switch. It is part of the MC14051B series, which includes the MC14052B (dual 4-channel) and MC14053B (triple 2-channel) models. The MC14051BDG is designed for controlling analog signals across a wide supply voltage range and features low ON impedance and very low OFF leakage current, making it suitable for various analog switching applications.
