Description
ISO7721QDRQ1 Automotive Dual-Channel Digital Isolator
The ISO7721QDRQ1 is an automotive, reinforced dual-channel digital isolator with one forward and one reverse channel. It supports data rates up to 100 Mbps, a 2.25 V to 5.5 V supply range and -40°C to 125°C operation in an 8-pin SOIC package.
What ISO7721QDRQ1 Is Designed to Do
The ISO7721QDRQ1 is an automotive, reinforced dual-channel digital isolator with one forward and one reverse channel. It supports data rates up to 100 Mbps, a 2.25 V to 5.5 V supply range and -40°C to 125°C operation in an 8-pin SOIC package. Final suitability depends on the complete circuit, software, thermal, mechanical, qualification and lifecycle requirements.
For sourcing, the base family name is not enough. The full ISO7721QDRQ1 ordering code, package, packing format, revision or grade, source condition and required inspection evidence should be confirmed against the actual order.
- Channels / direction: 2 channels, 1 forward and 1 reverse
- Maximum data rate: 100 Mbps
- Isolation rating: 3,000 VRMS for D package per UL 1577
Key Selection Characteristics
Channels / direction: 2 channels, 1 forward and 1 reverse
This capacity or architecture detail helps determine whether the device fits the processing, storage, conversion or channel requirements of the target design.
Maximum data rate: 100 Mbps
Use this performance point to confirm timing, throughput, interface compatibility and system-level margin before selecting the ordering code.
Isolation rating: 3,000 VRMS for D package per UL 1577
This verified characteristic helps identify the intended device variant and should be reviewed together with the complete electrical, mechanical and lifecycle requirements.
