well the reason I ask about the letters is because I used to build
little B.E.A.M. robots. For those, I needed the exact letter to be
correct. for example, one time I needed some 74hc14s. My local
electronics store said "well, we've got the 7414.. those should work
fine" I bought a bunch of them, tried them out, and no luck. They
did NOT work. Ordered some of the 74hc14's and they worked fine.
I just dont want to run into similar issues, only w/ a tun of IC's
that ive ordered online already, then have to wait a week before I can
start my project again.
In that particular case I think it was because the HC's could process
the signals faster.. something like that
