Product Description
The CM1223 family of diode arrays has been designed to provide ESD protection for electronic components or sub-systems requiring minimal capacitive loading. These devices are ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading.

Features
• 2, 4, and 8 channels of ESD protection with integrated backdrive protection on all lines
• Provides ESD protection to IEC61000-4-2 Level 4
    - 8kV contact discharge
    - 15kV air discharge
• Low channel input capacitance of 1.0pF typical
• Minimal capacitance change with temperature and voltage
• Channel I/O to Gnd capacitance difference of 0.02pF typical is ideal for differential signalsl
• Mutual capacitance between signal pin and adjacent signal pin - 0.11pF typical
• Zener diode protects supply rail and eliminates the need for external by-pass capacitors
• Pin compatible with CM1213-02, -04, and -08
• Each I/O pin can withstand over 1000 ESD strikes
• Available in SOT, and MSOP packages
• Lead-free version available
