    Bi-Directional 4 Channel Logic Level Converter

     1,000

    This tiny logic level shifter features four bidirectional channels, allowing for safe and easy communication between devices operating at different logic levels. It can convert signals as low as 1.5 V to as high as 18 V and vice versa, and its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.
