3 / 12 page PRODUCT SPECIFICATION FAN6550 REV. 1.0.2 3/11/02 3 Absolute Maximum Ratings Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. Operating Conditions Electrical Characteristics Unless otherwise specified, AVCC = VDD = PVDD = 3.3V ±10%, TA = Operating Temperature Range (Note 1) Notes 1. Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions. 2. AVCC, PVDD = 3.3V ±10% Parameter Min. Max.
