TXS0102DCUR - Texas Instruments - 2-BIT BIDIRECTIONAL VOLTAGE-LEVEL TRANSLATOR FOR OPEN-DRAIN APPLICATIONS

Quick Detail:

2-BIT BIDIRECTIONAL VOLTAGE-LEVEL TRANSLATOR FOR OPEN-DRAIN APPLICATIONS

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 1.65 V to 3.6 V while it tracks the VCCA supply, and the B ports supporting operating voltages from 2.3 V to 5.5 V 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 1.8-V, 2.5-V, 3.3-V, and 5-V 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.

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:

• No Direction-Control Signal Needed

• Max Data Rates

• UART – 24 Mbps (Push Pull)

• GPIO – 2 Mbps (Open Drain)

• Available in the Texas Instruments NanoStar™ DCT OR DCU PACKAGE

Package (TOP VIEW)

• 1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on B port (VCCA ≤ VCCB)

• VCC Isolation Feature – If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State

• No Power-Supply Sequencing Required –Either VCCA or VCCB Can Be Ramped First

• I DQE OR DQM PACKAGE off Supports Partial-Power-Down Mode
