I've just encountered some datasheets for parts
that I've never heard
of before -- 74ABTxxx parts. The lack of a "C" in there would seem
to indicate TTL of some sort but looking at the datasheet the power
supply current would seem to indicate CMOS of some sort, it's in the
uA range.
Anybody ever encountered these before?
I note that packaging seems to be _only_ surface-mount
styles.
I think I have some, though I'll have to check when I get home - but
what I have is definitely DIPs, not SMT. If I'm right, ie, if what I
have really is 74ABTxxx, then they're CMOS chips with TTL-compatible
interfaces, ie, you can connect them directly to real 74xxx TTL logic.
