Texas Instruments TXB0106/TXB0106-Q1 Level-Shift & Volt Translators

Texas Instruments TXB0106/TXB0106-Q1 Level-Shifting and Voltage Translators are 6-bit non-inverting translators that utilize two separate configurable power-supply rails. The A port accepts any supply voltage from 1.2V to 3.6V and is designed to track the V_CCA voltage. The B port accepts any supply voltage from 1.65V to 5.5V and is designed to track the V_CCB voltage. This feature allows for universal low-voltage bidirectional translation between any of the voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V). The V_CCA voltage must not exceed the V_CCB voltage.

All outputs are placed in the high-impedance state when the output-enable (OE) input is low. The TXB0106 is designed so that the OE input circuit is supplied by VCCA. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry prevents damaging current backflow through the device during power down by disabling the outputs.

To verify the high-impedance state during power-up or power-down, tie the OE to the GND through a pulldown resistor. The driver's current-sourcing capability determines the minimum value of the resistor. The Texas Instruments TXB0106-Q1 devices are AEC-Q100 qualified for automotive applications.
