DC CHARACTERISTICS
–40 °C < T_amb < +125 °C; 5.5 V < V_BAT < 16 V; –0.3 V < V_TxD < 5.5 V; –0.3 V < V_NSTB < 5.5 V; –0.3 V < V_EN < 5.5 V; –0.3 V < V_RxD < 5.5 V;
–1 V < V_CANH < +16 V; bus load resistor at pin RTH: 2 kΩ < R_T < 9.2 kΩ; total bus load resistance 270 Ω < R_L < 9.2 kΩ;
C_L < 13.7 nF; 1µs < R_L ∗ C_L < 4µs; RxD pull-up resistor 2.2 kΩ < R_d < 3.0 kΩ; RxD: loaded with C_LR < 30pF to GND;
all voltages are referenced to pin 8 (GND); positive currents flow into the IC;
typical values reflect the approximate average value at V_BAT = 13 V and T_amb = 25 °C, unless otherwise specified.
