Thanks... what i need is only the hold/pause function for Q and Q_bar (pin 10,11).. from your reply, i hope that can be done..While the 4047 has several flipflops in it, none of them are configured as data latches (if that's what you meant by "memory"). As for the hold/pause, both the True and Complement Gating inputs allow this. BUT - as indicated in the logic diagram on page 2 of the datasheet, pausing the astable terminates the current clock cycle. If the output (pin 13) already was in the low state, it just sits there. If it was in the high state, it drops low immediately and sits there. Thus, when enabled the oscillator always starts out with a clean first cycle.
