Overview
The CD4067BEG4 is a 16-channel analog multiplexer or demultiplexer integrated circuit produced by Texas Instruments. This device is part of the CD40x7B series and is known for its high-voltage rating and low ON resistance, making it suitable for a variety of analog and digital signal switching applications.
The CD4067B features binary address decoding on-chip, allowing for the selection of any one of the 16 channels using four binary control inputs (A, B, C, D) and an inhibit input. The inhibit input can turn all channels off when a logic '1' is applied.
