Pin 1 the emitter of output transistor, in H-bridge applications can drive the low-side transistor. With strobe input You can switching off the output independently from inputs state. I mean this function need in second application (railway), because the only way to give stop.
 
Oh,Ok.
Now I understand.
so, strobe is switch.
It must be connected to positive with resitor to activate this comparator?

Thanks Very much Sebi
