🚦 TXS0108E 8-Channel Bi-Directional Logic Level Converter Module

The TXS0108E 8-Channel Logic Level Converter is a powerful, high-performance module designed to bridge the gap between systems using different logic voltage levels.¹ Built around the advanced TXS0108E chip, this device offers eight independent, bi-directional channels, making it perfect for connecting complex bus systems or multiple peripherals between ²$3.3\text{V}$ and ³$5\text{V}$ logic.⁴

This module is an ideal solution for engineers and hobbyists needing to interface microcontrollers (like Arduino or ESP32) with various sensors, displays, and devices.

✨ Key Features and Performance

FeatureTechnical DetailAdvantage8 ChannelsConverts up to 8 logic signals simultaneously.Ideal for converting full 8-bit data buses or multiple interfaces (I2C, SPI, UART) at once.Automatic Bi-DirectionalFeatures internal logic for automatic direction control.No external programming or direction pins needed; simplifies integration and use.Wide Voltage RangeLow (A) side: $1.2\text{V}$ to $3.6\text{V}$; High (B) side: $1.65\text{V}$ to $5.5\text{V}$.Compatible with virtually all modern microcontroller logic levels.Application OptimizedOptimized for open-drain applications (like I2C) but supports standard CMOS push-pull translation.Versatile enough for both bus communication and general purpose I/O.Output Enable (OE)Dedicated pin for enabling/disabling outputs.Useful for low-power applications as it shuts off pull-up resistors, dropping idle current to a few $\mu\text{A}$.Power Sequencing SafeNot affected by power supply sequencing.No risk of damage if one side is powered before the other.

🔌 Module Connections and Operation

The module requires power input on both the low and high voltage sides, and the ground must be common to both systems.⁵

Connect to VA to enable always, or use a pull-down resistor to ground for MCU control.

🛠️ Assembly and Best Practices

• Assembly: The module comes with two strips of 10-pin male headers.⁶ For best alignment, insert the headers into a breadboard first, then place the module on top and solder the pins.
• 
  
• Optimal Use: The auto-direction sensing is ideal for dedicated bus systems (like I2C and SPI).
• Caution: Due to the auto-sensing logic, this module is not recommended for randomly switching GPIO pins or circuits with strong external pull-up resistors, as this can confuse the automatic direction switching.
