The 40-735 data communications multiplexer is designed for switching the data lines of serial interfaces (RS232, USB). Careful attention to the design of the module ensures that the switching system minimizes its impact on the transmission distance of USB1.1 interfaces.

The MUX is available in 36:1 or 18:1 formats and enables a single source of serial data to be switched to one of 36 or 18 devices under test. This allows the data source to load information to, or receive information from, the device under test. This 36:1 version can be software configured into two independent 18 way MUXs enabling two separate sources of serial data to be connected to separate banks of 18 devices. 

The module is ideal for performing bulk testing of any device that relies on a serial data communications port to load software or control the device operation. It can also be used for a variety of other applications where ever a 2-pole low power MUX is required.
