Texas Instruments TXB0108DQSR Environmental and export classification status description

of Texas Instruments TXB0108DQSR The TXB0108DQSR is an 8-bit, bidirectional voltage-level translator designed to translate signals between different voltage domains, typically ranging from 1.2V to 5.5V. It is particularly useful for interfacing devices operating at different voltage levels without requiring external resistors. Functions - Bidirectional Operation: The device allows signals to be translated in both directions. - Automatic Direction Sensing: It automatically detects the direction of the data flow, eliminating the need for control signals. - High-Speed Operation: Supports data rates up to 100 Mbps. - Wide Supply Voltage Range: Compatible with a range of input/output voltage levels from 1.2V to 5.5V. Applications - I²C and SPI interfaces: Used for level shifting between different I²C or SPI voltage levels. - Interfacing mixed-voltage systems: Suitable for applications where devices with different operating voltages need to communicate. - Microcontrollers and peripherals: Often used to connect microcontrollers to sensors, memory devices, and other peripherals that operate at different voltage levels. Alternative Parts - TXB0104: A smaller 4-channel version of the TXB0108, suitable for applications that require fewer channels. - TXS0108E: Another bidirectional level shifter with additional features tailored for I²C and similar applications. - FTDI FT232RL: Offers USB to UART communications with level shifting capabilities but is more specialized for USB interfaces. Embedded Modules While the TXB0108 itself is not typically found as a standalone embedded module, it can be integrated into custom PCBs designed for specific applications. Additionally, it may be featured in development boards that include various interface components. Related Q&A Q1: What is the maximum data rate supported by the TXB0108DQSR?
