Overview
The CD4067BPW, produced by Texas Instruments, is a 16-channel analog multiplexer or demultiplexer integrated circuit. It is part of the CD40x7B series, which features high-voltage types with a 20V rating. This device is digitally controlled and includes four binary control inputs (A, B, C, D) and an inhibit input, allowing for the selection of one of the 16 channels. The CD4067BPW is particularly useful for expanding the number of analog inputs or outputs in electronic circuits due to its low ON resistance, high-speed switching, and very low quiescent power dissipation.
