Overview
The CD4097BM, produced by Texas Instruments, is a CMOS analog multiplexer or demultiplexer. This device is part of the CD40x7B series, known for its high-voltage ratings and low ON resistance. It is a digitally controlled analog switch with internal address decoding, making it versatile for various analog and digital multiplexing applications. The CD4097BM is particularly useful in scenarios requiring the selection of one of several analog input signals and routing them to a common output, or vice versa when used as a demultiplexer.
