use 555s but makethe common 555 timer chip can have the input voltage levels tweaked by means of the control voltage pin, so put 3V or so on the control voltage pin to get it compatible with 5V input on the triggerCMOS signals and threshold pins by putting 5V intowire one 555 as an inverter and the control-voltage pinother as a monostable.
