CAN controller interface
PCA82C250
CHARACTERISTICS
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.
