概要
Description
That exact designation does not map to a publicly listed ISO standard. ISO standards are usually shown as “ISO 7342” (without long suffixes) or “ISO/IEC …,” and typically don’t include strings like CQDWRQ1. The suffix is more likely a vendor SKU, revision, or internal project code.
Likely possibilities:
- A vendor’s product/model code or internal reference.
- A misread or composite of a standard number plus a product tag.
What to do:
- Check the source document for the exact title or scope.
- Search the ISO Catalogue for “ISO 7342” (and variants) to confirm if a standard exists.
- If you have the industry or issuer, provide it and I can help identify the correct standard or specification.

Pinout
Pin count: 8 pins.
Function: ISO7342CQDWRQ1 is a dual-channel, bidirectional digital isolator that provides isolation between two sides of the circuit (two isolated I/O channels), typically used to protect a microcontroller or logic from high-voltage or noisy domains.
