High speed is a very relative term here. It's high speed compared
to the 4000 series, it's is not high speed in modern terms.
If you want speed, then look for the AC* or LV* families.
Like always: check the data sheets of the parts to see whether
they fit your need. NXP and fairchild have general guides on
logic families and their characteristics online.
