Each of the four outputs will sink 600 m A in the ON state. The outputs have a minimum breakdown voltage (load dump) of 60 V and a sustaining voltage of 40 V. The inputs are patible with TTL and 5 V CMOS logic systems and include internal pull-down resistors to ensure that the outputs remain OFF if the inputs are open-circuited. Over-current protection for each channel has been designed into these devices and is activated...
