Hello to all, I have this project developed with a 16F74. Now that I go for a small series, could I use the 16C74(A), which I think is more easily available and maybe cheaper. As far as I can see on the data sheets they are functionally equivalent. The F74 data sheet also mentions 'pin-compatible to C74A', but I just want to make sure they are functionally equivalent as well. Any inputs highly appreciated!
