16. Vγ is the forward diode voltage. Typically (over the complete temperature) Vγ = 1 V.
17. By one of the trimming bits, following reconfiguration can be done during chip−level testing in order to fit the NCV7420_5 into different
interface: pins TxD and EN will have typ. 10 kW pull−down resistor to ground and pin WAKE will have typ. 10 mA pull−up current source.
