Product Introduction

Overview

The TXS0101DCKR is a 1-bit bidirectional voltage-level translator produced by Texas Instruments. This device is designed for open-drain and push-pull applications and is packaged in a SOT-SC70 (DCK) package with 6 pins. It allows for low-voltage bidirectional translation between various voltage nodes such as 1.8V, 2.5V, 3.3V, and 5V. The device features two separate configurable power-supply rails, VCCA and VCCB, which can operate within the ranges of 1.65V to 3.6V and 2.3V to 5.5V, respectively. This flexibility makes it suitable for a wide range of applications requiring voltage level translation.

Key Features

  • Latch-up performance exceeds 100mA per JESD 78, class II.
  • ESD protection exceeds JESD 22 standards.
  • No direction-control signal needed.
  • 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.
  • Supports partial-power-down mode operation.
  • Available in the Texas Instruments NanoFree™ package.
  • Output-enable (OE) input to place all outputs in a high-impedance state when set to low.

Applications

The TXS0101DCKR is versatile and can be used in various applications requiring voltage level translation, such as:

  • Interface between different voltage domains in mixed-voltage systems.
  • Communication between devices operating at different voltage levels.
  • Level shifting in embedded systems, industrial control systems, and consumer electronics.
  • Applications where ESD protection and latch-up immunity are critical.

Q & A

  1. What is the package type of the TXS0101DCKR?
    The TXS0101DCKR is packaged in a SOT-SC70 (DCK) package with 6 pins.
  2. What are the operating voltage ranges for VCCA and VCCB?
    VCCA operates from 1.65V to 3.6V, and VCCB operates from 2.3V to 5.5V.
  3. What are the maximum data rates for push-pull and open-drain configurations?
    The maximum data rate for push-pull is 24 Mbps, and for open-drain, it is 2 Mbps.
  4. Does the TXS0101DCKR require a direction-control signal?
    No, the TXS0101DCKR does not require a direction-control signal.
  5. What is the ESD protection level for the A and B ports?
    The A port has ESD protection of 2500V Human-Body Model, 200V Machine Model, and 1500V Charged-Device Model. The B port has ESD protection of 8kV Human-Body Model, 200V Machine Model, and 1500V Charged-Device Model.
  6. How does the VCC isolation feature work?
    If either VCC input is at GND, both ports are placed in the high-impedance state.
  7. Is power-supply sequencing required for the TXS0101DCKR?
    No, either VCCA or VCCB can be ramped first without any sequencing requirement.
  8. What is the purpose of the output-enable (OE) input?
    The OE input places all outputs in a high-impedance state when set to low.
  9. What is the recommended way to handle the OE input during power transitions?
    Tie OE to GND through a pull-down resistor to ensure proper functioning during power transitions.
  10. Is the TXS0101DCKR RoHS compliant?
