Product Description
The CM1216 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 (V
P
) or
negative (V
N
) supply rail. The CM1216 will protect
against ESD pulses up to
+
15kV per the IEC 61000-4-2
standard.
This device is particularly well-suited for protecting sys-
tems 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 CM1216 family of devices is available with
optional lead-free finishing.
