技术特性

• 4 data-line protection
• Protects VBUS
• Very low capacitance: 3 pF typ.
• SOT23-6L package
• RoHS compliant
• Benefits
  • Very low capacitance between lines to GND for optimized data integrity and speed
  • Low PCB space consumption, 9 mm² maximum foot print
  • Enhanced ESD protection: IEC 61000-4-2 level 4 compliance guaranteed at device level, hence greater immunity at system level
  • ESD protection of VBUS: allows ESD current flowing to ground when ESD event occurs on data line
  • High reliability offered by monolithic integration
  • Low leakage current for longer operation of battery powered devices
  • Fast response time
  • Consistent D+ / D- signal balance:
    • Best capacitance matching toleranceI/O to GND = 0.015 pF
    • Compliant with USB 2.0 requirements < 1 pF
• Complies with the following standards
  • IEC 61000-4-2 level 4:
    • 15 kV (air discharge)
    • 8 kV (contact discharge)
