CM1641 Datasheet, PDF (1/10 Pages) ON Semiconductor – 4-Channel Low Capacitance Dual-Voltage ESD Protection Array

4-Channel Low Capacitance Dual-
Voltage ESD Protection Array
CM1641
Features
• Three channels of low voltage ESD protection
• One channel of high voltage ESD protection
• Provides ESD protection to IEC61000-4-2 Level
4:
±8kV contact discharge (Pins 1-3)
±15kV 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
*Standard test condition is IEC61000-4-2 level 4 test circuit with each pin subjected to ±8kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one continuous
test run. The part is then subjected to standard production test to verify that all of the tested parameters are within spec after the 1000 strikes.
