- 1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on B port (VCCA ≤ VCCB)
- VCC Isolation Feature – If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State

- Ioff Supports Partial-Power-Down Mode Operation
This one-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 3.6 V. The B port is designed to track VCCB. VCCA must be less than or equal to VCCB. VCCB accepts any supply voltage from 2.3 V to 5.5 V. This allows for low voltage bidirectional translation between any of the 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 pull-down resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
