CM1224 - 2- and 4-Channel Low Capacitance ESD Protection Arrays

General Description

The CM1224 family of diode arrays has been designed to provide ESD protection for electronic components or subsystems requiring minimal capacitive loading.

These devices are ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading.

Key Features

  • Two or four channels of ESD protection Provides ESD protection to IEC61000-4-2 Level 4.
  • ±8kV contact discharge Low channel input capacitance of 0.7pF typical Minimal capacitance change with temperature and voltage Channel input capacitance matching of 0.02pF typical is ideal for differential signals Zener diode protects supply rail and eliminates the need for external by-pass capacitors L.
