XISO1500DBQR Texas Instruments Integrated Circuit (Small Outline Packages) In Stock

What are the key features of XISO1500DBQR?

• 3 kVRMS basic isolation rating eliminates the need for a separate optocoupler or digital isolator, reducing BOM cost and PCB area in RS-485 industrial network nodes
• Supports RS-485 and RS-422 differential bus standards at data rates up to 500 kbps, enabling robust long-distance communication in noisy industrial environments
• Ultra-small SSOP-8 package integrates driver and receiver with isolation in a footprint under 20 mm², replacing multi-chip solutions in space-constrained designs

What is XISO1500DBQR used for?

The XISO1500DBQR targets industrial fieldbus nodes, motor drive control panels, and building automation controllers where RS-485 communication must be electrically isolated from high-voltage motor or power circuitry. Its 3 kVRMS isolation rating protects low-voltage MCU systems from ground potential differences of up to hundreds of volts that commonly appear between separated equipment enclosures. Designers use it in PLC I/O modules, energy meters, and distributed sensor networks where a compact, integrated solution is preferred over a discrete optocoupler plus RS-485 driver combination.
