Product description
Module with a TMUX4051 and peripheral components. The TMUX4051 is an improved variant of the classic analog multiplexer CD4051, capable of switching bipolar signals (max ±12V) with logic signals down to 1.8V without the need for external level conversion. The TMUX4051 also has lower internal resistance, typically 60 ohms compared to 125 ohms for the CD4051. Additionally, the board has a transistor mounted to invert the Enable signal, allowing two boards to be connected in parallel to multiplex or demultiplex up to 16 channels. The board is normally configured for 8 channels with Enable. When Enable is inverted by moving the solder bridge on the back of the board, Enable becomes the "D" input, and by sending a 4-bit address, you can switch between 16 different channels.
An analog multiplexer is used, for example, when you want to read multiple analog signals into an ADC or send an analog signal to several different locations. The multiplexer also works just as well with digital signals and is bidirectional.
