The Logic Level Shifter Module from Whadda provides eight logic conversion channels to enable microcontrollers, sensors, and modules with different logic level voltages to communicate with one another. Each channel is fully bidirectional and is compatible with both open-drain and push-pull logic drivers. The module can be used to convert 3.3 V to 5 V, 1.8-3.3 V, and other common logic levels.
It is recommended to pull the Output Enable pin high with a pull-up resistor to ensure that the outputs are properly enabled. If the different logic level data lines need to be isolated, the Output Enable line can be pulled low, which will put all of the I/O channels in a high-impedance state.
