[1] VCCI is the supply voltage associated with the data input port.

[2] VCCO is the supply voltage associated with the output 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.

[4] For non bus hold parts only (74LVC2T45).
