Overview
The MC14051B, produced by onsemi, is an analog multiplexer/demultiplexer that effectively implements an 8-channel single-ended (SP8T) solid-state switch. This device is part of a family that includes the MC14052B (dual 4-channel) and MC14053B (triple 2-channel) analog multiplexers. These devices are digitally controlled analog switches designed to handle analog signals across a wide supply voltage range.
The MC14051B is known for its low ON impedance, very low OFF leakage current, and linearized transfer characteristics, making it suitable for various analog switching applications. It also features triple diode protection on control inputs and a break-before-make switch function.
