CM1641

• 3 channels of low voltage ESD protection
• 1 channel of high voltage ESD protection
• Provides ESD protection to IEC61000-4-2 Level 4:
  • ?kV contact discharge (Pins 1-3)
  • ?5kV contact discharge (Pin 4)
• Low channel input capacitance
• Minimal capacitance change with temperature and voltage
• High voltage zener diode protects supply rail
• No need for external bypass capacitors
• Each I/O pin can withstand over 1000 ESD strikes*
• RoHS compliant, lead-free finish

The CM1641 comprises a 4-channel, low-capacitance, dual voltage ESD protection device available in a low profile, RoHS compliant, lead-free UDFN package.
