Description
KAmodTXB0108 is a module with the TXB0108 system from Texas Instruments. The system is an 8-channel voltage translator. Thanks to the built-in direction detection system, the module provides two-way signal flow without the need to use an additional pin. Thanks to its small dimensions, the product can be used in many development projects.
The TXB0108 system is designed for applications with push-pull outputs (e.g. SPI, SD card). For cooperation with open collector outputs, e.g. for I2C communication, our other module KAmodTXS0108 is better suited.

Schematic
Connection
Power supply: The converter requires power from two different sources. The higher voltage (from 1.7 V to 5.5 V) should be connected to the pin marked as VCC_B, and the lower voltage (from 1.2 V to 3.6 V) should be connected to VCC_A.
Ground: Both devices and the converter must have a common ground, so the ground wire should be connected to the pin marked as GND.
Logical signals: Signals should be connected to the appropriate connectors. Higher voltage signals should be connected to Bx connectors, and lower voltage signals to Ax connectors.
