Product Introduction

Overview

The TXB0101DBVT from Texas Instruments is a 1-bit bidirectional voltage-level shifter designed for translating logic voltage levels between different voltage domains. This device operates with two separate configurable power-supply rails, allowing for universal low-voltage bidirectional translation between various voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. The TXB0101 features auto-direction sensing, eliminating the need for a direction-control signal, and includes edge rate accelerators to enhance data rates. It is available in a SOT-23 (DBV) package with 6 pins and is part of Texas Instruments' NanoFree™ package technology, which uses the die as the package itself.

Key Features

  • Auto-direction sensing with no need for a direction-control signal.
  • Operates with two separate configurable power-supply rails: VCCA (1.2 V to 3.6 V) and VCCB (1.65 V to 5.5 V).
  • Edge rate accelerators (one-shots) to improve data rates.
  • Low power consumption: maximum ICC of 5 µA.
  • Supports partial-power-down mode operation with Ioff circuitry).
  • High ESD protection: Human Body Model (HBM) and Charged-Device Model (CDM)).
  • Output-enable (OE) input to place all outputs in high-impedance state when low).
  • Available in Texas Instruments' NanoFree™ package technology).

Applications

The TXB0101DBVT is suitable for various applications requiring voltage translation between different voltage domains. These include:

  • Low-voltage logic translation in mixed-voltage systems).
  • Interface between different voltage level devices such as microcontrollers, memory, and peripherals).
  • Power management and sequencing in multi-voltage systems).
  • Industrial and consumer electronics where voltage level shifting is necessary).

Q & A

  1. What is the primary function of the TXB0101DBVT?

    The primary function of the TXB0101DBVT is to perform bidirectional voltage-level shifting between different voltage domains.

  2. What are the operating voltage ranges for the A and B ports?

    The A port operates from 1.2 V to 3.6 V, and the B port operates from 1.65 V to 5.5 V.

  3. What is the significance of the OE input in the TXB0101DBVT?

    The OE (output-enable) input is used to disable the device by setting it low, which places all outputs in a high-impedance state.

  4. What kind of ESD protection does the TXB0101DBVT offer?

    The device offers high ESD protection, exceeding ±2000 V for the A port and ±15 kV for the B port under the Human Body Model (HBM), and ±1500 V under the Charged-Device Model (CDM).

  5. Can the TXB0101DBVT be used in partial-power-down applications? off circuitry that disables the outputs when either VCC is switched off.

  6. What is the maximum power consumption of the TXB0101DBVT?

    The maximum power consumption (ICC) is 5 µA.

  7. What is the thermal resistance of the TXB0101DBVT in the SOT-23 package?

    The junction-to-ambient thermal resistance (RθJA) is 192.3 °C/W.

  8. Can external pullup or pulldown resistors be used with the TXB0101DBVT?

    Yes, but they must be kept higher than 50 kΩ to avoid contention with the output drivers.

  9. Is the TXB0101DBVT suitable for open-drain signal translation?

    No, for open-drain signal translation, devices from the TI TXS010X series should be used instead.

  10. What is the significance of the NanoFree™ package technology used in the TXB0101DBVT?

    The NanoFree™ package technology uses the die as the package itself, representing a major breakthrough in IC packaging concepts.
