logic families

[jovabiot]

in terms of delay time or max. frequency wich of this bipolar logic families is better? ALS,S,F or LS....

And from this CMOS families?? HC,AC or ACT

Thanks

Get the datasheets of a NAND gate and a D flipflop from each family. Look at propagation delay (Tpd) for the NAND gates, and maximum clock frequency (Fmax) for the flipflops. This will give you a pretty good idea of the speed of each family.
The generic NAND is 74xx00. The D FF is 74xx74.
