Pad

The exposed pad at the bottom surface of the package is designed for thermal
performance. Use of a center pad on the PCB is strongly recommended for ther-
mal conductivity as well as to provide mechanical stability of the package on the
PCB. The center pad is recommended to be solder masked defined with open-
ing size less than or equal to the exposed thermal pad on the package bottom to
prevent solder bridging to the outer leads of the device. Thermal vias must be
connected to GND plane as the thermal pad of package is at GND potential.
Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain.
