    3.3V-5V TXS0108E 8 Channel Bidirectional Logic Level Converter


    This chip allow easy conversion between logic levels allowing easy interfacing of Modules or other integrated circuits to a microcontroller or Arduino system.

    • 1.2 V to 3.6 V on A Port and 1.65 to 5.5 V on B Port
    • Output Enable Function Using OE pin
    • VCCA connects to lower logic level eg 3.3V
    • VCCB connects to higher logic level eg 5V
    • When Ax has TTL 3.3V input, Bx will get TTL 5V output
    • When Bx has TTL 5V input, Ax will get TTL 3.3V output
    • NO direction control required

    Example applications are Arduino to GSM connections, 3.3V SPI/I2C module connection to 5V system, UART interfacing between systems operating at different voltages

    Bi-Directional 4 Channel Logic Level Converter


    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.
