16 / 60 page  Analog Integrated Circuit Device Data 16 Freescale Semiconductor 33889 ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS Table 5. Dynamic Electrical Characteristics VSUP From 5.5 V to 18 V, V2INT from 4.75 to 5.25 V and TJ from -40°C to 150°C unless otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
