The TS3A24159 device can be properly operated without any external components. However, it is recommended to connect the unused pins to ground through a 50-Ω resistor to prevent signal reflections back into the device. It is also recommended that the digital control pins (IN1 and IN2) be pulled up to V_CC or down to GND to avoid undesired switch positions that could result from the floating pin.

Select the appropriate supply voltage to cover the entire voltage swing of the signal passing through the switch because the TS3A24159 input/output signal swing through NO and COM are dependant of the supply voltage V_CC.
