Product Description
The CM1293 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. Each ESD channel consists of a pair of diodes in series which steer the positive or negative ESD current pulse to either the positive (VP) or negative (VN) supply rail.

Features
• 2, 4, and 8 channels of ESD protection
• Provides ESD protection to IEC61000-4-2
    - 8kV contact discharge
    - 15kV air discharge
• Low loading capacitance of 2.0pF max.
• Low clamping voltage
• Channel I/O to I/O capacitance 1.5pF typical
• Zener diode protects supply rail and eliminates the need for external by-pass capacitors
• Each I/O pin can withstand over 1000 ESD strikes
• Available in SOT, and MSOP packages
• Lead-free version available

Applications
• DVI ports, HDMI ports in notebooks, set top boxes, digital TVs, LCD displays
• Serial ATA ports in desktop PCs and hard disk drives
• PCI Express ports
• General purpose high-speed data line ESD protection
