Is there a minimum propogation delay for the HC04? All the specs I have mention 10ns typical and 18ns maximum (at 4.5 volts Vcc), but is there a minimum delay time? I need 20ns of delay in a line, and want to make sure it's going to take at least that amount of time... Should I use a couple of HC04s? Four of them? Will four guarantee 20ns delay? In another line I need 10ns delay, but it passes through an HC273 edge triggered flipflop which has a typical propogation delay of 17ns. Can I just assume that the output of the HC273 flipflop will be stable for at least 10ns before switching over to a new value? Dazed and confused about propogation delays and life in general, jeremym@fraser.sfu.ca
