The TMUX7219M can be operated without any external components except for the supply decoupling capacitors. All inputs passing through the switch must fall within the recommended operating conditions, including signal range and continuous current. For this design, with a dual supply of ±15 V, the signal range can range from -15 V to +15 V. Industrial applications such as factory automation and control and test and measurement benefit from using a 2:1 switch, because it allows additional flexibility in the design. A single 2:1 switch has numerous applications such as switching between an analog signal path and a calibration path, and allowing a single channel to be configured as either an analog input or analog output.
