●At the time of data output of each P.C., DATA and POL., output transistor will become ON(Negative logic electrically).
● At the time of OVR output, output transistor will at the OVER signal will become ON(Negative logic electrically). Moreover, for all of the
output transistor will become OFF (Positive logic electrically) at the time of OVER output. (However, for the POL., normal OFF at the “OL”,
DATA, and normal ON at the “－OL”).
