why is a NAND GATE faster than a AND gate and NOR gate? thx
i'm still not quite sure, can you explain it further? thx very muchHere are a couple of example datasheets from TI.
AND gate
NAND gate
Take a look at the typical circuit for the 7400 and the 7408 in the linked-to datasheets from TI. The reason for the difference in speed is tied to the propagation from input to output. See if you can spot why it takes longer for a signal change on the input to manifest itself on the output of these two different gates.

In the attachment, you will notice that the AND gate has an additional inverter stage in its typical circuit that is absent in the NAND gate.i'm still not quite sure, can you explain it further? thx very much
