STMicroelectronics L6364 Dual Channel Transceiver IC
STMicroelectronics L6364 Dual Channel Transceiver IC is designed to support the IO-Link standard making it suitable for industrial sensor applications. The L6364 acts as a bridge between a microcontroller with a sensor or actuator function and a 24V supply and signaling cable.
The STMicroelectronics L6364 Dual Channel Transceiver IC is configured by the microcontroller via the SPI interface at startup, in normal operation. This configuration then allows the L6364 to typically operate as a Single Input Output IOLink device driving the output lines as configured by the microcontroller. The IO-Link master can initiate communication and exchange data with the microcontroller while the L6364 acts as a physical layer for communication.
