Frequently Asked Questions

Q: What is the ISO3080DWR and what does it do?

A: The ISO3080DWR is an isolated RS-485 / RS-422 transceiver integrated circuit housed in a SOIC-16 surface-mount package. It provides galvanic isolation between the logic-side (microcontroller or host) and the bus-side (RS-485 / RS-422 network), protecting your system from ground loops, common-mode voltage differences, and electrical transients that are common in industrial environments.

Q: Are these chips new or refurbished?

A: These are brand-new ISO3080DWR components in original condition — not refurbished, reclaimed, or pulled from existing boards. Each order includes 2 pieces.

Q: What package type is the ISO3080DWR and how do I solder it?

A: The ISO3080DWR comes in the standard SOIC-16 (Small Outline IC, 16-pin) surface-mount package. It can be soldered using standard SMT reflow oven processes or hand-soldered with a fine-tip iron. The SOIC-16 footprint is widely supported by PCB design tools and is straightforward to integrate into new or existing board layouts.

Q: Is this chip compatible with Modbus RTU networks?

A: Yes. Since Modbus RTU and ASCII protocols run over RS-485 physical layer, the ISO3080DWR is fully compatible and is commonly used in Modbus-based industrial control and automation systems.
