Texas Instruments TXB0104D

The Texas Instruments TXB0104D is a 4-bit bidirectional voltage-level shifter designed for universal low-voltage translation between different voltage nodes. This device is part of the voltage-level translator family and is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) package. It features automatic direction sensing, allowing it to translate signals in both directions without the need for explicit direction control. The TXB0104D is suitable for a wide range of applications where voltage level translation is necessary, such as in mixed-voltage systems and interface circuits.

• Automatic Direction Sensing: The device automatically senses the direction of data flow, eliminating the need for explicit direction control.
• Universal Voltage Translation: Supports translation between various voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V).
• Low Power Consumption: Maximum I_CC of 5 µA.
• ESD Protection: Exceeds JESD 22 standards with ±15 kV Human-Body Model (A114-B) and 1500 V Charged-Device Model (C101) on the B port.
• Output Enable (OE): OE input circuit referenced to V_CCA, allowing outputs to be placed in a high-impedance state when OE is low.
• V_CC Isolation Feature: If either V_CC input is at GND, all outputs are in the high-impedance state.
• Partial Power-Down Mode Operation: Supported through I_OFF feature.

• Mixed-Voltage Systems: Ideal for systems where different voltage levels are used, ensuring seamless communication between components.
• Interface Circuits: Used in various interface circuits where voltage level translation is necessary, such as in USB, I²C, SPI, and other communication protocols.
• Consumer Electronics: Suitable for use in consumer electronics where multiple voltage levels are common, such as in smartphones, tablets, and laptops.
• Industrial Automation: Used in industrial automation systems where different voltage levels are required for various components.
• Automotive Systems: Applicable in automotive systems where mixed-voltage environments are prevalent.
