Description

The CM1220 ESD protection arrays are available in four and eight channel configurations. Each ESD channel features a nominal capacitance of 14 pF making the devices ideal for protecting high speed I/O ports and LCD and camera data lines without significantly affecting signal integrity. The CM1220 integrates avalanche?type ESD diodes on every channel, providing a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). These diodes safely dissipate ESD strikes of ±15 kV, exceeding the maximum requirement of the IEC61000?4?2 international standard. Using the MIL?STD?883 (Method 3015) specification for Human Body Model (HBM) ESD, the CM1220 protect against contact discharges at greater than ±30 kV.
