CM1223
Industry First Low Capacitance ESD Protection Arrays w/Backdrive Protection
Features
2, 4, and 8 channels of ESD protection with inte-
grated backdrive protection on all lines
Provides ESD protection to IEC61000-4-2 Level 4
- 8kV contact discharge
- 15kV air discharge

protection
Product Description
The CM1223 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 neg-
ative ESD current pulse to either the positive (VP) or
negative (VN) supply rail. A Zener diode is embedded
between VP and VN, absorbing positive ESD strikes
and also providing ESD protection for the VP rail. An
additional diode is added in this device to serve as
backdrive current protection. The CM1223 will protect
against ESD pulses up to
±8kV per the IEC 61000-4-2
standard and using the MIL-STD-883D (Method 3015)
specification for Human Body Model (HBM) ESD, all
pins are protected from contact discharges of greater
than
±15kV.
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 and other applications
where extremely low loading capacitance with ESD
protection are required in a small package footprint.
The CM1223 family of devices is available with optional
lead-free finishing.
