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
