ELECTRICAL CHARACTERISTICS
DYNAMIC ELECTRICAL CHARACTERISTICS
DYNAMIC ELECTRICAL CHARACTERISTICS
Table 4. Dynamic Electrical Characteristics
All characteristics are for the analog chip only. Please refer to the specification for 68HC908EY16 for characteristics of the
microcontroller chip. Characteristics noted under conditions 9.0 V ≤ VSUP ≤ 16 V, -40°C ≤ TJ ≤ 125°C unless otherwise noted.
Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions unless otherwise noted.
