GENERAL DESCRIPTION

This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65V to 5.5V while it tracks the VCCA supply, and the B ports supporting operating voltages from 2.3V to 5.5V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.8V, 2.5V, 3.3V, and 5V voltage nodes.

When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. OE has an internal pull-down current source, as long as VCCA is powered.

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.

APPLICATIONS

I2C BUS

Portable POS Systems

Smart Card Readers

Cell-Phones

GPS

Portable Communication Devices

FEATURES

No Direction-Control Signal Needed

Data Rates
24Mbps (Push-Pull)
2Mbps (Open-Drain)

1.65V to 5.5V on A Ports and 2.3V to 5.5V on B Ports (VCCA ≤ VCCB)

VCC Isolation: If Either VCC is at GND, Both Ports are in the High-Impedance State

No Power-Supply Sequencing Required, Either VCCA or VCCB can be Ramped First

IOFF: Supports Partial-Power-Down Mode Operation

Available in QFN3.5x3.5-14L, TQFN3x3-16L, FO-12L package.
