6-Pack TXB0108 / TXS0108 8-Channel Level Shifter

• KIT WITH BOTH VARIANTS (3x TXB0108 + 3x TXS0108) Includes 3 TXB0108 (push-pull optimized) and 3 TXS0108 (push-pull & open-drain compatible) 8-bit bidirectional voltage shifters — for mixing 3.3V and 5V logic in projects with Arduino, Raspberry Pi, ESP32-S3, or sensor interfacing.
• AUTOMATIC DIRECTION SENSING No direction control pins needed. Translates signals between voltage levels from 1.2V–3.6V (A-side) to 1.65V–5.5V (B-side), with data rates up to 100 Mbps for high-speed applications.
• CHOOSE THE RIGHT VARIANT TXB0108 suits push-pull GPIO and digital signals like SPI; TXS0108 supports open-drain protocols like I2C (with pull-up resistors). Pick based on your protocol.
• COMPACT & EASY TO USE Breakout boards with headers for breadboard prototyping. 8 independent channels per module for multi-signal conversion without additional components.
• TEXAS INSTRUMENTS CHIPS Built with Texas Instruments TXB0108/TXS0108 ICs for low power consumption and ESD protection. Kit includes multiples of each type for backups or multiple projects.

Lonely Binary 6-Pack TXB0108 & TXS0108 8-Channel Bidirectional Level Shifter Kit

This 6-pack of 8-channel bidirectional voltage level shifters bridges different logic voltages. The kit includes 3 TXB0108 modules and 3 TXS0108 modules, giving flexibility to choose the right shifter for your application.

TXB0108 vs TXS0108

TXB0108: Optimized for push-pull applications, providing bidirectional drive for signal translation in standard digital interfaces like SPI. Suited for active high/low driving, not for open-drain setups.

TXS0108: Supports both push-pull and open-drain modes, suitable for protocols like I2C that rely on pull-up resistors. Features internal accelerators for faster edge rates.

Key Features

8 independent channels per module for multi-signal handling

Voltage range: 1.2V to 3.6V on one side, 1.65V to 5.5V on the other

Auto-direction sensing — no extra control logic needed

Compact PCB with pin headers for breadboards or custom circuits

Low quiescent current and ESD tolerance

For interfacing a 3.3V MCU with 5V sensors, building IoT devices, or prototyping with microcontrollers, this kit addresses voltage incompatibility. Includes multiples of each type for experimentation or repairs.
