ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions 5.5 V ≤ V_SUP ≤ 18 V, -40°C ≤ T_A ≤ 125°C for the 33912 and -40°C ≤ T_A ≤ 85°C for the
34912, unless otherwise noted. Typical values noted reflect the approximate parameter mean at T_A = 25°C under nominal
conditions, unless otherwise noted.

Notes
41. Parameters guaranteed for 7.0 V ≤ V_SUP ≤ 18 V.
42. Loss of local ground must not affect communication in the residual network.
43. Node has to sustain the current that can flow under this condition. Bus must remain operational under this condition.
44. This parameter is 100% tested on an Automatic Tester. However, since it has not been monitored during reliability stresses, Freescale
does not guarantee this parameter during the product's life time.
45. When over-temperature shutdown occurs, the LIN bus goes in recessive state and the flag LINOT in LINSR is set.
