3.3 V, 2 differential channel, 2 : 1 MUX/deMUX switch
6.2 Pin description
[1] DHVQFN20 package die supply ground is connected to both GND pins and exposed center pad. GND pins
and the exposed center pad must be connected to supply ground for proper device operation. For
enhanced thermal, electrical, and board level performance, the exposed pad needs to be soldered to the
board using a corresponding thermal pad on the board and for proper heat conduction through the board,
thermal vias need to be incorporated in the printed-circuit board in the thermal pad region.

normal operation. When HIGH, all
paths are switched off
(non-conducting high-impedance
state), and supply current
consumption is minimized.
