Overview
The CD4097BPWRE4, produced by Texas Instruments, is a CMOS analog multiplexer or demultiplexer. This device is part of the CD40x7B series and is known for its high-voltage rating and low ON resistance. It is a 16-channel multiplexer with four binary control inputs (A, B, C, D) and an inhibit input, allowing for the selection of any one of the 16 channels. The CD4097BPWRE4 is suitable for a variety of analog and digital multiplexing applications due to its low ON impedance, low OFF leakage current, and internal address decoding.
