CAN controller interface
Table 8. Characteristics …continued
VCC = 4.5 to 5.5 V; Tamb = 40 to +125 C; RL = 60 ; I8 > 10 A; unless otherwise specified; all voltages referenced to
ground (pin 2); positive input current; all parameters are guaranteed over the ambient temperature range by design, but only
100 % tested at +25 C.
