DESCRIPTION:

This is a 16-to-1 multiplexer module that is used to multiplex 16 inputs into 1 output. This module is suitable to monitor 16 sensors input (C0 to C15) with only 4 digital pins (S0 to S3). Also, the module accepts both digital and analog inputs compared to the conventional multiplexer that is only restricted to digital input.

Note: The onboard enable pin is active-low where high input on enable pin will switch off the board.
