Cmos are (were??) available in unbuffered (A) and buffered (B) variants from
memory. The difference is in the number of fets used to create each gate, as
well as a few clamping diodes etc. When a circuit is forcing a CMOS chip to
run in its linear region, it may be important to use the unbuffered variant,
if that is what the circuit calls for.
As for the exact meaning of the letters you have spelled out, I'm not sure.
Try checking NSC or one of the chip manufacturers on the web.
