P. C.
Note:
When P.C., DATA and POL. are all output, the output transistor switch turns ON
(negative logic). When ERROR is output, all DATA and POL. output transistors turn OFF
(positive logic).
Example 4: When the HOLD signal is input

HOLD
Note:
-
In this case, HOLD signal input operation is executed after a bridge of 100 ms or
more.
-
When the HOLD signal is input, the P.C. output transistor turns OFF (positive logic).
The P.C. HOLD signal turns OFF after one-shot operation.
