Overview
The CD4097BM96E4, produced by Texas Instruments, is a CMOS analog multiplexer or demultiplexer. This device is part of the CD40x7B series and is specifically designed for high-voltage applications, with a rating of up to 20V. It features a single 16-channel multiplexer or demultiplexer configuration, making it versatile for various analog and digital signal processing tasks. The CD4097B is digitally controlled, with four binary control inputs (A, B, C, D) and an inhibit input, allowing for precise selection of any one of the 16 channels. The device is known for its low ON resistance, high OFF resistance, and very low quiescent power dissipation, making it suitable for a wide range of applications.
