CM1223
Industry First Low
Capacitance ESD Protection
Arrays with Backdrive
Protection
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 (V P ) or negative (V N ) supply rail. A Zener diode is
embedded between V P and V N , to absorb positive ESD strikes and
provide ESD protection for the V P 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.
