9.2.2 Detailed Design Procedure

The TS5A2066 can be properly operated without any external components.

Unused signal path pins COM or NO maybe left floating or connected to ground through a 50-Ω resistor to prevent signal reflections back into the device.

TI recommends that the digital control pins (INX) be pulled up to VCC or down to GND to avoid undesired switch positions that could result from the floating pin. Leaving the logic pins floating may increase I_CC. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs (SCBA004), for further details.
