Broadcom Optocouplers ACFL-5211T bi-directional R2Coupler®

The Broadcom ACFL-5211T is an automotive grade dual-channel optocopler device designed for bi-directional digital communications.The device has two optocoupler channels internally aligned 180 degrees of each other, providing optimum chip pin-out configuration for bi-directional Tx/Rx data communication design and board layout. The two channels are electrically indepedent and galvanically isolated, providing an ideal isolated bi-directional power system communication interface.The device is optimized for low power systems supporting data rates up to 1 MBd.
