Logic Level Shifter, 4-Channel, Bidirectional

Description

This tiny logic level shifter features four bi-directional 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.
