HS1D datasheet by Taiwan Semiconductor

HS1D Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for HS1D?
  The recommended operating temperature range for HS1D is -40°C to 125°C, but it can be extended to -55°C to 150°C with proper derating.
• How do I handle the power-up sequence for HS1D?
  The power-up sequence for HS1D is critical. It's recommended to power up VDD first, followed by VCC, and then the input signals. A power-up sequence diagram is available in the application note.
• What is the maximum current rating for the HS1D output drivers?
  The maximum current rating for the HS1D output drivers is 20mA, but it's recommended to limit the current to 10mA for reliable operation and to prevent overheating.
• How do I implement ESD protection for HS1D?
  ESD protection for HS1D can be implemented using external ESD diodes or TVS devices. It's recommended to follow the ESD protection guidelines provided in the application note.
• What is the recommended PCB layout and routing for HS1D?
  The recommended PCB layout and routing for HS1D involves keeping the signal traces short and away from noise sources, using a solid ground plane, and following the layout guidelines provided in the application note.
