ISO721DG4 datasheet by Texas Instruments

ISO721DG4 Frequently Asked Questions (FAQs)

• What is the maximum data rate that the ISO721DG4 can support?
  The ISO721DG4 can support data rates up to 150 Mbps, but it's recommended to limit it to 100 Mbps for reliable operation.
• How do I ensure reliable operation of the ISO721DG4 in noisy environments?
  To ensure reliable operation in noisy environments, use proper PCB layout techniques, add noise filtering capacitors, and consider using shielding or a Faraday cage to reduce electromagnetic interference (EMI).
• What is the recommended power-up sequence for the ISO721DG4?
  The recommended power-up sequence is to apply VCC first, followed by VISO, and then the input signals. This ensures proper internal biasing and prevents latch-up.
• Can I use the ISO721DG4 in a multi-channel isolation application?
  Yes, the ISO721DG4 can be used in multi-channel isolation applications, but each channel must have its own isolated power supply and ground return to maintain isolation between channels.
• How do I handle the ISO721DG4's input/output voltage levels?
  The ISO721DG4 is a 5V device, but it can accept input voltage levels up to 5.5V. Ensure that the input voltage levels are within the recommended range to prevent damage or malfunction.
