Short-form specification
The data in a short-form
specification is extracted from a full data sheet with the
same type number and title. For detailed information see
the relevant data sheet or data handbook.
Limiting values definition
Limiting values given are in
accordance with the Absolute Maximum Rating System
(IEC 60134). 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
attheseoratanyotherconditionsabovethosegiveninthe
Characteristics sections of the specification is not implied.
Exposure to limiting values for extended periods may
affect device reliability.
