Industry First Low Capacitance ESD

Protection Arrays w/Backdrive Protection

CM1223

Features

Product Description

•

Two, four, and eight channels of ESD protection with

integrated backdrive protection on all lines

The CM1223 family of diode arrays are 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_Pand V_N, to absorb positive ESD

strikes and provide ESD protection for the V_Prail. An

additional diode is integrated to serve as backdrive current

protection. The CM1223 protects against ESD pulses up to

8kV per the IEC 61000-4-2 standard. In addition, all pins

•

Provides ESD protection to IEC61000-4-2 Level 4:

8kV contact discharge

15kV air discharge

•

Low channel input capacitance of 1.0pF (typical)

Minimal capacitance change with temperature and

voltage

•

Channel I/O to GND capacitance difference of 0.02pF

typical is ideal for differential signals

Mutual capacitance between signal pin and adjacent

signal pin at 0.11pF (typical)

Zener diode protects supply rail and eliminates the

need for external bypass capacitors

Pin compatible with CM1213-02, -04, and -08

Each I/O pin can withstand over 1000 ESD strikes*

Available in SOT, and MSOP packages

RoHS-compliant, lead-free packaging

are protected from contact discharges of greater than

15kV 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.

Applications

•

USB2.0 ports at 480Mbps in desktop PCs, notebooks

and peripherals

•

IEEE1394 Firewire ports at 400Mbps / 800Mbps

DVI ports, HDMI ports in notebooks, set top boxes,

digital TVs, LCD displays

The CM1223 family of devices are manufactured with

RoHS-compliant, lead-free packaging.

•

UDI and display ports

Serial ATA ports in desktop PCs and hard disk drives

PCI Express ports

General purpose high-speed data line ESD
