DESCRIPTION/ORDERING INFORMATION
This 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 1.65 V to 3.6 V. V_CCA must be less than or equal to V_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 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.
The TXS0104E is designed so that the OE input circuit is supplied by V_CCA.
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.
