General purpose high-speed data line ESD
protection
Product Description
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 (VP)
or negative (VN) supply rail. A Zener diode is
embedded
between
VP and VN, offering two
advantages. First, it protects the VCC rail 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.
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 loading capacitance with ESD
protection are required in a small package footprint.

*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.
