ISO7842FDWR Frequently Asked Questions (FAQs)

  • The maximum data rate is 150 Mbps, but it can be limited by the capacitance of the isolation barrier and the signal integrity of the system.
  • To ensure reliable operation, follow the recommended layout and routing guidelines, use a low-ESR capacitor for the VCC1 and VCC2 pins, and ensure the input signals are within the recommended common-mode voltage range.
  • The ISO7842FDWR can isolate up to 2500 Vrms for 1 minute, and 1500 Vrms continuous, but the maximum working voltage depends on the specific application and safety requirements.
  • Power sequencing is critical; ensure VCC1 and VCC2 are powered up simultaneously, and the input signals are stable before enabling the device. A soft-start circuit can help with power-up sequencing.
  • Keep the signal traces short and away from noise sources, use a solid ground plane, and ensure the isolation barrier is not compromised by vias or traces crossing the barrier.
