a. VCC is the positive power supply of the device core and input circuitry. VCC voltage defines the input threshold and levels

b. VCCA is the positive power supply of the bank A outputs. VCCA voltage defines bank A output levels

c. VCCB is the positive power supply of the bank B outputs. VCCB voltage defines bank B output levels. VCCB is internally connected to VCC.

d. VCCC is the positive power supply of the bank C outputs. VCCC voltage defines bank C output levels
