Connect VCCIO pins to either a 1.5-V, 1.8 V, 2.5-V, or 3.3-V power supply, depending
on the output requirements. The output levels are compatible with systems of the
same voltage as the power supply (that is, when VCCIO pins are connected to a 1.5-V
power supply, the output levels are compatible with 1.5-V systems). When VCCIO
pins are connected to a 3.3-V power supply, the output high is 3.3 V and is compatible
with 3.3-V or 5.0-V systems.
