Isolated RS-485/422 Transceivers (small package is available)

The CA-IS308x family of devices is a galvanically-isolated RS485/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 5000VRMS (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 CAIS308x 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.

The CA-IS308x series devices are available in wide-body SOIC16 package which is the industry standard isolated RS485/RS-422 package, and operate over -40°C to +125°C temperature range.
