Product Description

The CM1223 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.

Features

• Two, Four, and Eight Channels of ESD Protection with Integrated Backdrive Protection on all Lines

• Provides ESD Protection to IEC61000−4−2 Level 4: ±8 kV Contact Discharge & ±15 kV Air Discharge

• Low Channel Input Capacitance of 1.0 pF (typical)

• Minimal Capacitance Change with Temperature and Voltage

• Channel I/O to GND Capacitance Difference of 0.02 pF Typical is Ideal for Differential Signals

• Mutual Capacitance between Signal Pin and Adjacent Signal Pin at 0.11 pF (typical)

• Zener Diode Protects Supply Rail and Eliminates the Need for External Bypass 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

• These Devices are Pb−Free and are RoHS Compliant

Applications

• USB 2.0 Ports at 480 Mbps in Desktop PCs, Notebooks and Peripherals

• IEEE1394 Firewire® Ports at 400 Mbps / 800 Mbps

• DVI Ports, HDMI Ports in Notebooks, Set Top Boxes, Digital TVs, LCD Displays
