DC CHARACTERISTICS

–40

°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 kΩ < RT < 9.2 kΩ; total bus load resistance 270 Ω < RL < 9.2 kΩ;

CL < 13.7 nF; 1µs < RL ∗ CL < 4µs; RxD pull-up resistor 2.2 kΩ < Rd < 3.0 kΩ; 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.
