Description

Eight-channel bidirectional level shifters for connecting 3.3 V and 5 V logic. The pack mixes both chip types so you can match the shifter to the bus you are translating.

Highlights

• Both variants. Three TXB0108 boards for push-pull signals such as SPI and GPIO, and three TXS0108 boards for open-drain buses such as I2C.
• Automatic direction. No direction pin to drive: each channel senses which side is driving.
• Eight channels per board. Translate a whole parallel or multi-signal bus with one module.
• Breadboard-friendly. Breakout boards with 2.54 mm headers.

In the box

• 3 × TXB0108 8-channel board
• 3 × TXS0108 8-channel board
• 1 × storage case

Specifications

• Channels: 8 per board
• A side (low voltage): 1.2 to 3.6 V
• B side (high voltage): 1.65 to 5.5 V

Works with

Any microcontroller that needs to talk to parts on a different logic voltage, for example a 3.3 V ESP32-S3 driving 5 V peripherals.
