Not all EE's have the same education with regard to how semiconductors
function. When I was in school I took a class in semiconductor physics
- an entire semester on how the wee beasties function - more than most EEs.

If you can find real TTL, yes, I would say so. It's less
static-sensitive and it's more tolerant to things like hooking two
outputs together by mistake.
But note that there are many chips that have more or less TTL
