DESCRIPTION/ORDERING INFORMATION
This 8-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to
track V_CCA. V_CCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V_CCB. V_CCB
accepts any supply voltage from 1.65 V to 5.5 V. This allows for low-voltage bidirectional translation between any
of the 1.2-V, 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 state.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
