When the VCCIO pins are
connected to a 2.5–V power supply, the output levels are compatible with
2.5–V systems. When the VCCIO pins are connected to a 3.3–V power
supply, the output high is at 3.3 V and is therefore compatible with 3.3-V
or 5.0–V systems. Devices operating with VCCIO levels lower than 3.0 V
incur a nominally greater timing delay of tOD2 instead of tOD1. Inputs can
always be driven by 2.5–V, 3.3–V, or 5.0–V signals.
