[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.
[4] For non bus hold parts only (74LVC1T45).
