| 4-Channel Low Capacitance Dual-Voltage ESD Protection Array CM1241 Features * * * 3 channels of low voltage ESD protection 1 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 Block Diagram VP (Internal) VCC O O Pin 4 CH1 O Pin 1 CH2 O Pin 2 CH3 O Pin 3 Pins 6 - 8 VN Pin 5 GND (c)2010 SCILLC. All rights reserved. April 2010 - Rev. 3 Publication Order Number: CM1241/D CM1241 Typical Application *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.
