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

track VCCB. 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.

VCCA should not exceed VCCB.

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

are placed in the high-impedance state.

The TXB0106-Q1 device 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 when it is powered down.

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.
