8.3 Device Functional Modes

When the EN pin of the TMUX1204 is pulled high, one of the switches is closed based on the state of the address lines. When the EN pin is pulled low, all the switches are in an open state irrespective of the state of the address lines. The EN pin can be connected to V_DD (as high as 5.5 V).

The TMUX1204 can be operated without any external components except for the supply decoupling capacitors. Unused logic control pins should be tied to GND or V_DD 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 D) should be connected to GND.
