[1]

VCCO is the supply voltage associated with the output port.

[2]

VCCI is the supply voltage associated with the input port.

10. Static characteristics

[1]

VCCO is the supply voltage associated with the output port.

[2]

VCCI is the supply voltage associated with the data input port.

[3]

To guarantee the node switches, an external driver must source/sink at least IBHLO / IBHHO when the input is in the range VIL to VIH.
