CAN controller interface
Table 8. Characteristics …continued
VCC = 4.5 to 5.5 V; Tamb = −40 to +125 °C; RL = 60 Ω; I8 > −10 µA; 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.
