FUNCTIONAL DESCRIPTION
Refer to Figure 2.
The HD3SS212 behaves as a two to one using high bandwidth pass gates. The input port is selected using the
Dx_SEL pin according to Table 1.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any conditions beyond those indicated under recommended operating conditions
is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values, except differential voltages, are with respect to network ground terminal.
