14-2. Logic Change
Select the logic of output signals with pin No. 28.
When COM and pin No. 28 are open: negative logic
When they are short-circuited: positive logic
14-3. BCD Data Hold
The BCD data output signal is held. Switching is carried out by pin No. 27.
When COM and pin No. 27 are open: hold cancel
When they are short-circuited: hold on
14-4. Equivalent Circuit
・ Output
