This data sheet contains target or goal specifications for product development.
This data sheet contains final product specifications.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later.
Limiting values are given in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and
operation of the device at these or at any other conditions above those given in the Characteristics sections of
this specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
