Preliminary

CMOS IC

1-BIT BIDIRECTIONAL

LEVEL-SHIFTING AND

VOLTAGE TRANSLATOR WITH

AUTO DIRECTION-SENSING



DESCRIPTION

SOT-26

This 1-bit noninverting translator uses two separate configurable

power-supply rails. The A port is designed to track V_CCA. V_CCAaccepts

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

V_CCB. V_CCBaccepts 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. V_CCAshould not

exceed V_CCB

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

the high-impedance state.

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

using I_OFF. The I_OFFcircuitry 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 pull-down resistor; the

minimum value of the resistor is determined by the current-sourcing

capability of the driver.



FEATURES

* 1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port (V_CCA≤ V_CCB

)

* V_CCIsolation Feature – If Either V_CCInput Is at GND, All Outputs Are

in the High-Impedance State

* OE Input Circuit Referenced to V_CCA

* Low Power Consumption, 5μA Max I_CC

* I_OFFSupports Partial-Power-Down Mode Operation



APPLICATION

* Handset

* Smartphone

* Tablet

* Desktop PC
