16-bit I2C-bus and SMBus, low power I/O port with interrupt
5.2 Pin description
[1]
HVQFN24 and HWQFN24 package die supply ground is connected to both the VSS pin and the exposed
center pad. The VSS pin 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 PCB in the thermal pad region.
[2]
PCA9535 I/Os are totem pole, whereas the I/Os on PCA9535C are open-drain.
