The TMUXHS4212 has two power modes, active/normal operating mode and standby/shutdown mode. During standby mode, the device consumes very-little current to achieve ultra low power in systems where power saving is critical. To enter standby mode, the OEn control pin is pulled high through a resistor and must remain high. For active/normal operation, the OEn control pin should be pulled low to GND or dynamically controlled to switch between H or L.

The TMUXHS4212 consumes 180 μA of power when operational and has a shutdown mode exercisable by the OEn pin resulting < 2 µA.
