描述 Description

The CM1220 ESD protection arrays are available in four and eight channel configurations. Each ESD channel features a nominal capacitance of 14pF 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 ±15kV, 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 ±30kV.
