ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
All characteristics are for the analog chip only. Refer to the 68HC908EY16 specification for characteristics of the
microcontroller chip. Characteristics noted under conditions 9.0 V ≤ V_SUP ≤ 16 V, 0°C ≤ T_J ≤ 125°C unless otherwise noted.
Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal conditions unless otherwise noted.
