8.4 Device Functional Modes

The TMUX621x devices have four independently selectable single-pole, single-throw switches that are turned-on

or turned-off based on the state of the corresponding select pin. The control pins can be as high as 36V.

The TMUX621x devices can be operated without any external components except for the supply decoupling

capacitors. The SELx pins have internal pull-down resistors of 4MΩ. If unused, SELx pin must be tied to GND 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 connected to GND.
