Product Description

The CM1293A 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. Each ESD channel consists of a pair of diodes in series that steer the positive or negative ESD current pulse to either the positive (VP) or negative (VN) supply rail.

Features

• Two and four channels of ESD protection

• Provides ESD protection to IEC61000-4-2

• ±8kV contact 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 RoHS-compliant, lead-free SOT and

MSOP packages

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
