This parameter is guaranteed by process monitoring but is not production tested. 17. This parameter is guaranteed only if correct trimming was applied. 18. The high side HS3 can be only used for resistive loads. 19. This parameter is guaranteed by process monitoring but is not production tested. 20. 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 ≤ 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. Characteristic Symbol Min Typ Max Unit |
