This device is a 8-bit non-inverting level translator which uses two separate configurable power-supply rails. The A port tracks the V CCA pin supply voltage. The V CCA pin accepts any supply voltage between 1.4 V and 3.6 V. The B port tracks the V CCB pin supply voltage. The V CCB pin accepts any supply voltage between 1.65 V and 5.5 V. Two input supply pins allows for low Voltage bidirectional translation between any of the 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes.

When the output-enable (OE) input is low, all outputs are placed in the high-impedance (Hi-Z) state.

To ensure the Hi-Z state during power-up or power-down periods, tie OE to GND through a pull-down resistor. The minimum value of the resistor is determined by the current-sourcing capability of the driver.
