Active

Isolated RS-485/422 Transceivers

The CA-IS3082WW devices are reinforced isolated RS-485 transceivers which have excellent 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 up to 7.5- kVRMS (60s) of galvanic isolation of and typical ±150kV/μs CMTI. Isolation barrier improves communication quality by breaking ground loops and reducing noise where there are large differences in ground potential between ports. 

The CA-IS3082WW devices support multi-node data communication, and maximum data rate is up to 500kbps, allowing up to 256 transceivers (loads) on a common bus. The CA-IS3082WW devices are half-duplex transceivers, which could control the driver and receiver enable pins to avoid bus conflicts.

The CA-IS3082WW devices are available in 16-pin ultrawide-body SOIC package (creepage and clearance ≥ 15mm), and specified over extended industrial temperature range of –40°C to +125°C.
