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 1.2

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. 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 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.
