Overview
The CD4067BME4 is a 16-channel analog multiplexer/demultiplexer produced by Texas Instruments. This component is part of the CD4067B series, known for its high-voltage rating and low ON resistance. It is designed to switch one of 16 analog inputs to a single analog output or control multiple analog outputs with a single digital output. The CD4067BME4 is particularly useful in expanding the number of analog inputs or outputs in electronic circuits.
