15-2. Equivalent Circuit
- Output
The signal output circuit is operated through a TTL open collector.
- Input
15-3. Signal Input
Logic Switching (B14)
The output signal logic is switched. (The strobe signal logic is also switched.)
If open, negative logic will result, and if shorted with COM, positive logic will result.
BCD data hold (A14)
BCD data is held when shorted with COM.
No strobe pulse is output.
