18. This parameter is guaranteed by process monitoring but is not production tested.
19. This parameter is guaranteed only if correct trimming was applied
Table 3. Static Electrical Characteristics (continued)
All characteristics are for the analog chip only. Refer to the 68HC908EY16 datasheet for characteristics of the microcontroller
chip. Characteristics noted under conditions 9.0 V ≤ V
SUP
≤ 16 V, -40°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.
