Product description
8-channel bi-directional level shifter based on the TXB0108 for voltage level translation between different logic levels. The module can automatically detect signal direction and is suitable for communication between systems operating at for example 1.8V, 3.3V, and 5V. Suitable for digital interfaces such as GPIO, UART, and SPI. Not suitable for I2C since pull-up resistors interfere with the automatic direction detection. Supplied with pin headers.
