TXB0104QPWRQ1 General Description

Voltage-level translators address the challenges posed by simultaneous use of different supply-voltage levels on the same circuit board. This 4-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track V_CCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V_CCB. VCCB 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 should not exceed V_CCB.

When the output-enable (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 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.

The TXB0104 is designed so that 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, preventing damaging current backflow through the device when it is powered down.

Good quality spares and service ,thanks

Voltage adjusts, en pin never understood for what. It says there is a signal output but i did not find anything there by an oscillator. I found some datasheet, there is a synchronization input, but the leg is not the one). The seller did not answer the question.
