3.3 V, 2 differential channel, 2 : 1 MUX/deMUX switch for PCIe Gen3
[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.

Functional description
7.1 Function selection and shutdown function
The CBTL02043A/B provides a shutdown function to minimize power consumption when
the application is not active, but power to the CBTL02043A/B is provided. The XSD pin
(active HIGH) places all channels in high-impedance state (non-conducting) while
reducing current consumption to near-zero. When XSD pin is LOW, the device operates
normally.

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