The ports which are not selected by the Control Lines will be in High Impedance State.

8.4 Device Functional Modes

The HD3SS212 can be operated in normal operation mode or in shut down mode. In normal operation, the input

ports of the HD3SS212 are routed to the output ports according to Table 8-1. In shut down mode the HD3SS212

is disabled to enable power savings with a typical current consumption of 5 µA. The functional mode is selected

through the OE input pin with High for normal operation and LOW for shut down.
