°C < Tamb < +125 °C; 5.5 V < VBAT < 16 V; –0.3 V < VTxD < 5.5 V; –0.3 V < VNSTB < 5.5 V; –0.3 V < VEN < 5.5 V; –0.3 V < VRxD < 5.5 V;
–1 V < VCANH < +16 V; bus load resistor at pin RTH: 2 k < RT < 9.2 k; total bus load resistance 270 < RL < 9.2 k;
CL < 13.7 nF; 1s < RL CL < 4s; RxD pull-up resistor 2.2 k < Rd < 3.0 k; RxD: loaded with CLR < 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 VBAT = 13 V and Tamb = 25 °C, unless otherwise specified.
