7 / 100 page ![]() 7 1.0 CHARACTERISTICS AND SPECIFICATIONS Note: All data sheet minimum and maximum timing parameters are guaranteed over the rated voltage and temperature. Actual production testing is performed at TA =25 °C with an appropriate guardband to guarantee minimum and maximum timing specifications over rated voltage and temperature. 1.1 Absolute Maximum Ratings (VSS, VSSSD, PLLVSS = 0 V; all voltages with respect to 0 V) Caution: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. 1.2 Recommended Operating Conditions (VSS, VSSSD, PLLVSS = 0 V; all voltages with respect to 0 V) 1.3 Digital D.C. Characteristics for VDD Level I/O (TA =25 °C;VDD = 2.5 V; measurements performed under static conditions.)
