Notes
27.
AC characteristic according to ISO11898-3, tested per figure 5 and 6. Guaranteed by design, room temperature only.
28.
AC characteristic according to ISO11898-3, tested per figure 7. Max reported is the typical measurement under the worst condition (gnd
shift, dominant/recessive edge, at source or destination node. ref to ISO test specification). Guaranteed by design, room temperature
only.
Table 5. Dynamic Electrical Characteristics (continued)
VSUP From 5.5 V to 18 V, V2INT from 4.75 to 5.25 V and TJ from -40 to 150 °C, unless otherwise noted. Typical values noted
reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.
