Electrical Characteristics

2.1

Absolute Maximum Ratings

The absolute maximum ratings are stress ratings only. The ZSSC3154 might not function or be operable above

the recommended operating conditions. Stresses exceeding the absolute maximum ratings might also damage

the device. In addition, extended exposure to stresses above the recommended operating conditions might

affect device reliability. Renesas

does not recommend designing to the “Absolute Maximum Ratings.”

Parameters apply in operating temperature range and without time limitations.
