HVQFN24 and HWQFN24 package die supply ground is connected to both the V
center pad. The V
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 PCB in the thermal pad region.
PCA9535 I/Os are totem pole, whereas the I/Os on PCA9535C are open-drain.
