Overview
The CD4051BMG4, produced by Texas Instruments, is a CMOS single 8-channel analog multiplexer or demultiplexer with logic-level conversion. This device is part of the CD405xB series and is designed to handle a wide range of digital and analog signal levels. It features a single supply range of 3V to 20V and dual supply range of ±3V to ±10V, making it versatile for various applications. The CD4051B device includes three binary control inputs (A, B, and C) and an inhibit input, allowing it to select one of eight channels to be turned on and connect one of the eight inputs to the output.
