The 4:1 Mux/Demux Digital Switching module is a single channel 4:1 switch which allows you to connect and switch between up to four digital I/Os (Input/Output) to a single digital IO. Typically it wil be used to select between S/PDIF sources and a single DAC, but could also be used with any digital signal.

Switching is controlled using the same 2-bit binary technique as the S/PDIF Mux Module and the 8-channel Buffalo DAC. This can be controlled by a digital solution, or with our 4-Input Selection Switch Kit (available below).

DC power for the module can be anything from 3.3V to 5.5V.

All channels can optionally use direct wiring, terminal blocks (included), 0.1" headers (not included), or U.FL coaxial connectors (available below).
