15MBd Dual-channel, Bi-directional R2Coupler® Optocoupler

Currently Viewing:

The Broadcom ACFL-6211T 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 high speed systems supporting data rates up to 15 MBd and packaged in a compact SSO-12 package comparable to the SSO-8 footprint. 
Broadcom R2Coupler isolation products provide the reinforced insulation and reliability needed for critical automotive and high temperature industrial applications.
