Texas Instruments  TXB0108DQSR

This 8-bit noninverting translator uses two separate configurable power-supply rails. TheA port is designed to track VCCA. VCCA accepts anysupply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB.VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows foruniversal 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. VCCA should not exceedVCCB.

When the output-enable (OE) input is low, all outputs are placed in the high-impedancestate.

The TXB0108 is designed so that the OE input circuit is supplied byVCCA.

This device is fully specified for partial-power-down applications usingIoff. The Ioff circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.

To ensure the high-impedance state during power-up or power-down, OE should be tied toGND through a pulldown resistor; the minimum value of the resistor is determined by thecurrent-sourcing capability of the driver.
