AC/DC Operating Conditions

Warning:

The values in this chapter are preliminary and subject to change.

9.1

Absolute Maximum Ratings

Table 9-1 lists absolute maximum ratings for the ICS1531. Stresses above these ratings can cause

permanent damage to the ICS1531. These ratings, which are standard values for ICS commercially rated

parts, are stress ratings only. Functional operation of the ICS1531 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.
