= 3.3 V, a MAX V device can drive a device with 5.0-V TTL inputs but not 5.0-V CMOS inputs. For 5.0-V CMOS, open-drain setting
= 1.8 V, a MAX V device can drive a 1.2-V or 1.5-V device with 1.8-V tolerant inputs.
= 2.5 V, a MAX V device can drive a 1.2-V, 1.5-V, or 1.8-V device with 2.5-V tolerant inputs.
= 3.3 V and a 2.5-V input signal feeds an input pin, the VCCIO supply current will be slightly larger than expected.
= 3.3 V, a MAX V device can drive a 1.2-V, 1.5-V, 1.8-V, or 2.5-V device with 3.3-V tolerant inputs.
