Parameters guaranteed for 7.0 V

≤ VSUP ≤ 18 V.

104.

When Over-temperature shutdown occurs, the LIN bus goes in recessive state and the flag LINOT in LINSR is set.

Table 33. Static Electrical Characteristics (continued)

Characteristics noted under conditions 5.5 V

≤ VSUP ≤ 18 V, -40°C ≤ TA ≤ 125°C for the 33910 and -40°C ≤ TA ≤ 85°C for the

34910, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal

conditions, unless otherwise noted.
