STMicroelectronics L6364

Dual channel transceiver IC for SIO and IO-Link sensor applications

L6364 is a dual channel transceiver for industrial sensor applications.

It has been designed to support the IO-Link standard and acts as a bridge between a microcontroller with a sensor or actuator function and a 24 V supply and signaling cable.

L6364 is configured by the microcontroller via the SPI interface at startup. L6364 operates as a Single Input Output IO-Link device driving the output lines as configured by the microcontroller. If the device is connected to an IO-Link master, then the master can initiate communication and exchange data with the microcontroller while the L6364 acts as a physical layer for the communication.
