ISO721DR Frequently Asked Questions (FAQs)

  • The maximum data rate of ISO721DR is 100 Mbps, but it can be limited by the capacitance of the isolation barrier and the signal transmission frequency.
  • To ensure signal integrity and minimize noise, use a low-ESR capacitor, keep the signal traces short, and use a ground plane to reduce electromagnetic interference (EMI).
  • TI recommends using a 0.1 μF ceramic capacitor and a 10 μF electrolytic capacitor in parallel, placed as close as possible to the VCC pin, to ensure stable power supply decoupling.
  • Yes, ISO721DR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure proper thermal management and consider derating the device's specifications accordingly.
  • The enable pin (EN) is active-low, so connect it to GND to enable the device. When EN is high, the device is in shutdown mode, reducing power consumption.
