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. 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. A Zener diode is

embedded between VP and VN, to absorb positive ESD strikes and

provide ESD protection for the VP rail. An additional diode is

integrated to serve as backdrive current protection. The CM1223

protects against ESD pulses up to ±8 kV per the IEC 61000−4−2

standard. In addition, all pins are protected from contact discharges of

greater than ±15 kV as outlined by the MIL−STD−883D (Method

3015) specification for Human Body Model (HBM) ESD.

These devices are particularly well−suited for protecting systems

using high−speed ports such as USB2.0, IEEE1394 (Firewire®,

iLink™), serial ATA, DVI, HDMI and corresponding ports in

removable storage, digital camcorders, DVD−RW drives, as well as

other applications where extremely low loading capacitance with ESD

protection are required in a small package footprint.
