10.1 Absolute Maximum Ratings
Table 10-1 lists the absolute maximum ratings for the ICS1892. Stresses above these ratings can cause
permanent damage to the ICS1892. These ratings, which are standard values for ICS commercially rated
parts, are stress ratings only. Functional operation of the ICS1892 at these or any other conditions above
those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods can affect product reliability. Electrical parameters are
guaranteed only over the recommended operating temperature range.
