Logic Change; Bcd Data Hold; Equivalent Circuit - Unipulse F370 Operation Manual

10.BCD DATA OUTPUT(OPTION)

10-2. Logic Change

Select the logic of output signals with pin No. 28.

10-3. BCD Data Hold

The BCD data output signal is held. Switching is carried out by pin No. 27.

10-4. Equivalent Circuit

・Output
The signal output circuit is operated through a TTL open collector.
