Chipanalog CA-IS3089WX Isolated Interface IC

Chipanalog CA-IS3089WX

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 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.
