I want to create a truth table to see all options for 74HC123 output. Basically an optocoupler output is connected to 74HC123 as input. 74HC123 will get the data from optocoupler. There could be two options "0" and "1".
Optocouple has 1 output and 74HC123 has 3 inputs. So i wanted to create truth table to see options for output data.
I did something like this:
74HC123 truth table:
Is it true? If it is wrong, how can i do it?
