IC Usage Considerations
[1] The absolute maximum ratings of a semiconductor device are a set of ratings that must not be
[2] Do not insert devices in the wrong orientation or incorrectly.
Some of the functional blocks, circuits, or constants in the block diagram may be omitted or simplified
for explanatory purposes.
The equivalent circuit diagrams may be simplified or some parts of them may be omitted for
explanatory purposes.
Timing charts may be simplified for explanatory purposes.
The application circuits shown in this document are provided for reference purposes only. Thorough
evaluation is required, especially at the mass production design stage.
Toshiba does not grant any license to any industrial property rights by providing these examples of
application circuits.
Components in the test circuits are used only to obtain and confirm the device characteristics. These
components and circuits are not guaranteed to prevent malfunction or failure from occurring in the
application equipment.
Notes on handling of ICs
exceeded, even for a moment. Do not exceed any of these ratings.
Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result
injury by explosion or combustion.
Make sure that the positive and negative terminals of power supplies are connected properly.
Otherwise, the current or power consumption may exceed the absolute maximum rating, and
exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result
injury by explosion or combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation
or incorrectly even just one time.
