Product Details

General Description

The CA-IS309x family of devices is galvanically-isolated RS-485/RS-422 transceivers with built-in isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs. All devices of this family have the logic input and output buffers separated by a silicon oxide (SiO2) insulation barrier that provides up to 5kVRMS (60s) of galvanic isolation and ±150kV/μs typical CMTI. Isolation improves data 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-IS309x family of devices is designed for high-speed multi-drop operation with high ESD protection of up to ±8kV HBM and ±12kV IEC 61000-4-2 Contact Discharge ESD protection on the bus pins. The receiver is 1/8-unit load, allowing up to 256 transceivers (loads) on a common bus. The CA-IS3090 and CA-IS3096 full-duplex transceivers are designed for bidirectional data communications on multipoint bus transmission lines simultaneously. The CA-IS3092 and CS-IS3098 provide half-duplex 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. See the Ordering Information for the different duplex, data rate and VISO level options.

The CA-IS309x series devices are available in wide-body 20-pin SOIC and 16-pin SOIC packages which are the industry standard isolated RS-485/RS-422 package, and operate over -40°C to +125°C temperature range.
