8.4 Device Functional Modes

The TMUX110x devices have a controllable single-pole, single-throw switch that is turned on or turned off based

on the state of the corresponding select pin. The control pin can be as high as 5.5V.

The TMUX110x devices can be operated without any external components except for the supply decoupling

capacitors. Unused logic control pins should be tied to GND or VDD in order to ensure the device does not

consume additional current as highlighted in Implications of Slow or Floating CMOS Inputs. Unused signal path

inputs (Sx or Dx) should be connection to GND.
