3 Description

Voltage-level translators address the challenges

posed by simultaneous use of different supply-voltage

levels on the same circuit board. This 4-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 should not exceed

VCCB.

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

outputs are placed in the high-impedance state. To

establish 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 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.
