The
SN74LVCH8T245 is optimized to operate with VCCA and VCCB set at 1.65 V to 5.5 V. The A port is designed to
track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB
accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation
between any of the 1.8-V, 2.5-V, 3.3-V, and 5.5-V voltage nodes.
