TXS0104EDR 4-Bit Bidirectional Voltage-Level Translator SOIC-14

This TXS0104EDR 4-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. VCCA must be less than or equal to VCCB. The B port is designed to track 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.

The TXS0104EDR is designed so that the OE input circuit is supplied by VCCA. 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.
