Ultra-small Isolated RS 485/422 Transceivers with DC-DC Converter
The CA-IS2092A 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. The transceivers have the logic input and output buffers separated by a silicon oxide (SiO2) insulation barrier that provides up to 2.5kVRMS (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-IS2092A is designed for multi-drop operation with high ESD protection of up to ±8kV Human Body Model (HBM) on the bus pins. The receiver is 1/8-standard-unit load, allowing up to 256 transceivers (loads) on a common bus. The CA-IS2092A provides half-duplex transceivers.This device provides slow slew rate to minimize EMI and reflections, allowing for error-free data transmission up to 0.5Mbps. The individual logic supply input allows fully compatible 2.5V to 5.5V logic on logic input lines.
The CA-IS2092A device is available in LGA16 package and operates over -40°C to +125°C temperature range.
