TXS0104E - 4-Bit Bidirectional Voltage-Level Shifter for Open-Drain and Push-Pull Applications

This 4-bit non-inverting translator uses two separate configurable power-supply rails.The A port is designed to track V_CCA. V_CCA acceptsany supply voltage from 1.65 V to 3.6 V. V_CCA must be less than or equal toV_CCB. The B port is designed to track V_CCB.V_CCB accepts any supply voltage from 2.3 V to 5.5 V. This allows forlow-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltagenodes.

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

The TXS0104E is designed so that the OE input circuit is supplied byV_CCA.

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.
