5. General Buffer And Comparator Drive Block
The KA3050 is composed of 5 general buffers and a comparator.
This block has 10 inputs and 6 outputs.
All output are controlled by MC and SC codes except MGO.
The control codes are as follows.
The NES and SC

are conflict with each other, it means.
NES = High
