CAN transceiver for 24 V systems
Table 8. Characteristics â¦continued
VCC = 4.5 V to 5.5 V; Tamb = ï40 ï°C to +125 ï°C; RL = 60 ï; I8 > ï10 ïA; 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 ï°C.
