The CA-IS308x family of devices is a galvanically-isolated RS- 485/RS-422 transceiver that has superior isolation and  RS485 performance to meet the needs of the industrial  applications. All devices of this family have the logic input  and output buffers separated by a silicon oxide (SiO₂)  insulation barrier that provides galvanic isolation, features  up to 5000V_RMS (60s) of galvanic isolation and ±150kV/μs  typical CMTI. Isolation improves communication by  breaking ground loops and reduces noise where there are  large differences in ground potential between ports. 

The CA-IS308x family of devices supports multiple nodes communications on bus line, and max data rate up to  20Mbps, allowing up to 256 transceivers (loads) on a  common bus. Maintaining multidrop operation and  increasing the maximum data rate offers a more robust  system design for reliable communication. For the CA- IS308x family of devices, The CA-IS3080 and CA-IS3086 fullduplex transceivers are designed for bidirectional data  communications on multipoint bus transmission lines  simultaneously. The CA-IS3082 and CS-IS3088 provide halfduplex transceivers, the driver and receiver enable pins let  any node at any given moment be configured in either  transmit or receive mode which decreases cable  requirements.
