A vintage computer I'm working on has a 74F244N (20 pin DIP package) which I want to desolder, place in a socket and possibly replace (just in case something goes wrong), but my supplier (Farnell) no longer sells it.
According to Wikipedia's 7400-series article the "F" designation appears to indicate "fast" (well, that's my interpretation anyway) as it explains:
I found 12 currently available types of the '244 (DIP-20 package) at Farnell excluding the slower 74, 74LS and 74S series mentioned above):
SN74HC244N
CD74HCT244E
SN74ABT244AN
CD74AC244E
SN74HCT244N
CD74ACT244E
SN74ACT244N
SN74AC244N
CD74HC244E
SN74AHCT244N
SN74LVC244AN
SN74AS244AN
Can I replace the 74F244N with any of the above?
I read something about CMOS variants not always being compatible with TTL types. Those are the ones with "HC" somewhere in the name, aren't they?

The 74F family was introduced by Fairchild Semiconductor and adopted by other manufacturers; it is faster than the 74, 74LS and 74S families.
