If you want to hit the FET's harder with direct drive use a 74ACT part to drive them. You will get 24 ma drive with a "normal" part and >=48 ma with a "buffer" part (one example is the 74ACT125 at 75 ma). That's way more than the 10K pull up is feeding the output FET shown on the pdf of the schematic that I have. If you want to go crazy, there are dedicated driver chips, or you can parallel gates....both take up room that seems to be in short supply. How ever much current you can move, it's just while switching. You still move nothing in the static state. (sorry if part of that drifts off into the obvious .... :)-D:)-D)
