The CM1214A ESD protector is used to protect bipolar signal lines
against electrostatic discharge (ESD).
The CM1214A allows operation in high−speed environments with
signals levels up to ±5 V. The CM1214A comes in two versions:
• The CM1214A−01SO is a single channel ESD protector and is
available in a 3−lead SOT23−3 package.
• The CM1214A−02MR is a dual channel ESD protector and is available
in an 8−lead MSOP−8 package. The low sub−1 pF loading capacitance
makes the CM1214A−01SO ideal for protecting high−speed interfaces
including RF switches and amplifiers. The CM1214A−02MR is ideal for
dual high−speed signal pairs used in Gigabit Ethernet, ADSL, etc.
The CM1214A−02MR can also be used for higher transmit voltage
applications by connecting the two channels in series.
