CA-IS3092W
Active
Reinforced Isolated RS485/422 Transceivers with DC-DC Converter
The CA-IS309x family of devices is galvanically-isolated RS-485 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 ±20kV HBM on the bus pins. The receiver is 1/8-unit load, allowing up to 256 transceivers (loads) on a common bus. The CA-IS3092W/CA-IS3092VW and CA-IS3098W/CA-IS3098VW 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. The individual logic supply input of CA-IS3092VW and CA-IS3098VW devices allows fully compatible 2.7V to 5.5V logic on logic input/output lines.
The CA-IS309x series devices are available in wide-body 16-pin SOIC package which are the industry standard isolated RS-485 package, and operate over -40°C to +125°C temperature range.
