Working Principles

The TXS0104EDR is a bidirectional level shifter that translates logic levels between different voltage domains. It operates by monitoring the input signal levels and automatically adjusting the direction of translation. When the input signal is at a higher voltage level than the reference voltage (VREF), the IC translates the signal from the high-voltage domain to the low-voltage domain. Conversely, when the input signal is at a lower voltage level than VREF, the IC performs the translation in the opposite direction.

Detailed Application Field Plans

The TXS0104EDR is commonly used in various applications where voltage level translation is required. Some of the typical application fields include:

  1. Microcontrollers: Enables communication between microcontrollers operating at different voltage levels.
  2. Sensor Interfaces: Facilitates connectivity between sensors and microcontrollers with different voltage requirements.
  3. Communication Systems: Allows interfacing between devices with varying logic voltage levels, such as UART, I2C, SPI, etc.
  4. Battery-Powered Devices: Supports voltage level translation in portable electronic devices with limited power supply options.
  5. Industrial Automation: Provides level shifting capabilities in industrial control systems with mixed voltage domains.
