Product Overview
ADM3491ARZ-REEL7 is a 3.3 V Slew Rate Limited, Half- and Full-Duplex, RS-485/RS-422 Transceivers from Analog Devices. The exact order code is preserved for BOM, RFQ and incoming-inspection control. The verified package for this listing is SOIC-14. For engineering selection, the most relevant confirmed values include Type Transceiver, Voltage – Supply 3V~3.6V, Data Rate 10Mbps, Communication Mode Full-Duplex.
Application Fit
- Industrial serial networks
- RS-485/RS-422 field interfaces
- Multipoint communication links
Design Considerations
- Check data rate against cable length and bus topology.
- Use termination and biasing appropriate to the actual network.
- Verify supply voltage, duplex mode, ESD/isolation requirements and exact package before substitution.
