DESCRIPTION

The UTC UTXB0104 is 4-bit non-inverting 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 State 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 ensure the high-impedance state

during power up or power down, OE should be tied to GND through

a pull-down resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the driver.

The UTC UTXB0104 is designed so that the OE input circuit is

supplied by VCCA.

This device is fully specified for partial-power-down applications

using IOFF circuitry disables the outputs, preventing damaging

current backflow through the device when it is powered down.

FEATURES

* 1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port  (VCCA ≤ VCCB)

* VCC Isolation Feature – If Either VCC Input Is at GND, All Outputs  Are in the High-Impedance State

* OE Input Circuit Referenced to VCCA

* Low Power Consumption, 5μA Max ICC

* IOFF Supports Partial-Power-Down Mode Operation
