Hi Everyone.

I have some questions about Tri-State Buffer/Line Drivers and Optocouplers that handle In/Out Digital data lines.

I have a circuit that uses Tri-State buffer 74HCT541 to send and receive data from and to Optocouplers. Some of them are one directional and some are bidirectional. I want to make sure that and tests that all the Tri-State buffer IC and Optocoupler IC are functional by looking at Input and Output ends. Can you advise and suggest some of the easiest approaches for this type of circuit?. Again the circuit contains all Optocouplers and 74HCT541 with some +5V regulator IC. That is all.
Much appreciated.
