Notes

24.

Guaranteed by design

25.

Dominant to recessive slew rate is dependant upon the bus load characteristics.

AC Characteristics measured according to schematic Figure 4

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°C to 150°C unless otherwise noted. Typical values

noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
