Product Details

General Description

The CA-IS2092W is isolated half-duplex RS-485/RS-422 transceiver with internal isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs. This device has the logic input and output buffers separated by a silicon oxide (SiO2) insulation barrier that provides up to 2.5kVRMS galvanic isolation and ±150kV/μs typical CMTI that improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports. An integrated DC-DC converter generates the 3.3V or 5V operating voltage for the cable-side.

The CA-IS2092W is available in wide-body SOIC16 package which is the industry standard isolated RS-485/RS-422 package, and operates over -40°C to +125°C temperature range.
