3 Description

This 6-bit noninverting translator uses two separate

configurable power-supply rails. The A port is

designed to track VCCA. VCCA accepts any supply

voltage from 1.2V to 3.6V. The B port is designed

to track VCCB. VCCB accepts any supply voltage from

1.65V to 5.5V. This allows for universal low-voltage

bidirectional translation between any of the 1.2V, 1.5V,

1.8V, 2.5V, 3.3V, and 5V voltage nodes. VCCA must

not exceed VCCB.

When the output-enable (OE) input is low, all outputs

are placed in the high-impedance state.

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 disables

the outputs, preventing damaging current backflow

through the device during power down.

To verify the high-impedance state during power up

or power down, tie the OE to the GND through a

pulldown resistor; the minimum value of the resistor

is determined by the current-sourcing capability of the

driver.
