25 / 156 page  Analog Integrated Circuit Device Data Freescale Semiconductor 25 13892 ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS Table 6. Dynamic Electrical Characteristics Characteristics noted under conditions 3.1 V ≤ BATT ≤ 4.65 V, -40 ≤ T A ≤ 85 °C, GND = 0 V, unless otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions unless otherwise noted.
