7.3.1 Pin Current and Voltage Conventions

For reference purposes throughout the data sheet, current directions on their respective pins are as shown by the arrows in Figure 7-1. The direction is used to indicate the polarities of current in Specifications, but not to represent the actual current flow direction of each pin. All voltages are measured relative to the ground plane.
