TXS0108E Logic Level Converter – 8-Channel Bi-Directional Voltage Shifter Module (3.3V to 5V)

TXS0108E Logic Level Converter – Reliable 8-Channel Bi-Directional Voltage Shifting

The TXS0108E Logic Level Converter Module is an 8-channel, bi-directional voltage level shifter that allows safe and reliable communication between devices operating at different voltage levels. It is ideal for connecting 3.3V and 5V logic systems and is widely used in microcontroller, sensor, and module interfacing.

This module uses the TXS0108E IC, a high-speed, auto-direction sensing logic level translator from Texas Instruments. It supports data transfer in both directions on all 8 channels without requiring a direction control pin, making it incredibly easy to integrate into your projects.

Technical Performance and Compatibility

With support for voltage levels ranging from 1.2V to 3.6V on the low-voltage side (VCCA) and 1.65V to 5.5V on the high-voltage side (VCCB), this converter offers wide compatibility with modern digital systems including:

• Arduino, Raspberry Pi, ESP8266, ESP32

• AVR, ARM, and STM microcontrollers

• I2C, SPI, UART, and GPIO logic signals

The TXS0108E features high-speed operation up to 100 Mbps for push-pull signals and up to 2 Mbps for open-drain signals, making it suitable for both standard and high-speed communication protocols.

Compact and Easy to Use

The module comes in a compact PCB layout with clearly marked pins for quick wiring. With onboard pull-up resistors and auto-direction control, no manual switching is required. It’s perfect for:

• Logic level shifting between 3.3V sensors and 5V controllers
