This TXB0104 4-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 universal 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. V_CCA must not exceed V_CCB.

When the 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 must be tied to GND through a pulldown resistor The current sourcing capability of the driver determines the minimum value of the resistor.

The TXB0104 device is designed so the OE input circuit is supplied by V_CCA.

This device is fully specified for partial power-down applications using I _OFF. The I _OFF circuitry disables the outputs, which prevents damaging current backflow through the device when the device is powered down.

The TXB0104 device is designed so the OE input circuit is supplied by V_CCA.
