8.4.1 Switch Control Modes

Refer to the Section 8.2.

The HD3SS215 behaves as a two to one or one to two differential switch using high bandwidth pass gates. The input ports are selected using the AUX_SEL pin and Dx_SEL pin which are shown in Table 8-1.

(1) Z = High Impedance
(2) OE pin - For normal operation, drive OE high. Driving the OE pin low will disable the switch.
(3) The ports which are not selected by the control lines will be in high impedance status.
(4) For HDMI application, keep the AUX_SEL at middle level voltage. The AUX channel is still active, and the end user can make the lines float.
