MC33912BAC / MC34912BAC
Table 35. Static Electrical Characteristics (continued)
Characteristics noted under conditions 5.5 V ⤠VSUP ⤠18 V, -40°C ⤠TA ⤠125°C for the 33912 and -40°C ⤠TA ⤠85°C for the
34912, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal
conditions, unless otherwise noted.
