Datasheet
TXS0102 2-Bit Bidirectional Voltage-Level Translator datasheet (Rev. I)
 

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 pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

Features

  • No Direction-Control Signal Needed
  • Maximum Data Rates
    • 24 Mbps (Push Pull)
    • 2 Mbps (Open Drain)
  • Available in the Texas Instruments NanoStar™ Package
  • 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
  • Ioff Supports Partial-Power-Down Mode Operation
