ST10F269 21 - ELECTRICAL CHARACTERISTICS
139/184
21 - ELECTRICAL CHARACTERISTICS
21.1 - Absolute Maximum Ratings
Note: 1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
During overload conditions (V
IN
> V
DD
or V
IN
< V
SS
) the voltage on pins with respect to ground (V
SS
) must not exceed the values
defined by the Absolute Maximum Ratings.
21.2 - Parameter Interpretation
The parameters listed in the following tables represent the characteristics of the ST10F269 and its
demands on the system. Where the ST10F269 logic provides signals with their respective timing
characteristics, the symbol “CC” for Controller Characteristics, is included in the “Symbol” column.
Where the external system must provide signals with their respective timing characteristics to the
ST10F269, the symbol “SR” for System Requirement, is included in the “Symbol” column.
