8.3.1 Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.65-V to 5.5-V Power-Supply Range
Both VCCA and VCCB can be
supplied at any voltage between 1.65 V and 5.5 V making the device suitable for
translating between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V, and 5 V).
