ESD Warning: ESD (electrostatic discharge) sensitive
device. Although the MX6895 features proprietary
ESD protection circuitry, permanent damage may be
sustained if it is subjected to high energy electrostatic
discharges. Proper ESD precautions are
recommended to avoid performance degradation or
loss of functionality.
Note: The exposed thermal pad of the device package
must be connected to GND (ground).

4 Manufacturing Information
4.1 Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. Clare classified
all of its plastic encapsulated devices for moisture sensitivity according to the latest version of the joint
industry standard, IPC/JEDEC J-STD-020, in force at the time of product evaluation. We test all of our
products to the maximum conditions set forth in the standard, and guarantee proper operation of our
devices when handled according to the limitations and information in that standard as well as to any limitations set
forth in the information or standards referenced below.
Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced
product performance, reduction of operable life, and/or reduction of overall reliability.
This product carries a Moisture Sensitivity Level (MSL) rating as shown below, and should be handled according to
the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-033.
