ISO7231ADW datasheet by Texas Instruments

ISO7231ADW Frequently Asked Questions (FAQs)

• What is the maximum data rate that can be achieved with the ISO7231ADW?
  The maximum data rate is 100 Mbps, but it can be limited by the capacitance of the isolation barrier and the signal transmission frequency.
• How do I ensure reliable operation across the isolation barrier?
  To ensure reliable operation, follow the recommended layout and termination guidelines, and ensure that the input and output circuits are properly matched to minimize reflections and signal degradation.
• What is the maximum voltage that can be applied across the isolation barrier?
  The maximum voltage that can be applied across the isolation barrier is 2500 Vrms for 1 minute, but it's recommended to operate within the specified voltage range for reliable operation.
• How do I handle power-up and power-down sequencing with the ISO7231ADW?
  To avoid latch-up or other issues, ensure that the power supplies are sequenced correctly, with the VCC1 supply powering up before the VCC2 supply, and powering down in the reverse order.
• What is the typical propagation delay for the ISO7231ADW?
  The typical propagation delay is around 10 ns, but it can vary depending on the specific application, signal frequency, and operating conditions.
