8-Channel Low Capacitance ESD

Protection Arrays

CM1293

Features

Product Description

•

Eight channels of ESD protection

The CM1293 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 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, offering two advantages. First, it protects the

V_CCrail against ESD strikes, and second, it eliminates

the need for a bypass capacitor that would otherwise

be needed for absorbing positive ESD strikes to

ground. The CM1293 will protect against ESD pulses

up to ( 8kV contact discharge) per the IEC 61000-4-2

Level 4 standard.

Note: For 2 and 4 channel devices, see the

CM1293A datasheet.

Provides ESD protection to IEC61000-4-2

•

strikes*

•

Available in MSOP, lead-free packaging

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

protection

•

This device is 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

capacitance with ESD protection are required in a

small package footprint.

Block Diagram

*Standard test condition is IEC61000-4-2 level 4 test circuit with each pin subjected to 8kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one

continuous test run. The part is then subjected to standard production test to verify that all of the tested parameters are within spec after the 1000 strikes.
