ISO721DR datasheet by Texas Instruments

ISO721DR Frequently Asked Questions (FAQs)

• What is the maximum data rate that can be achieved with ISO721DR?
  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.
• How do I ensure signal integrity and minimize noise in my design?
  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).
• What is the recommended power supply decoupling for ISO721DR?
  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.
• Can I use ISO721DR in a high-temperature environment?
  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.
• How do I handle the enable pin (EN) in my design?
  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.
