... STABILITY o PER C DESCRIPTION The NE555 monolithic timing circuit is a highly stable controller capableof producing accuratetime delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external re- sistor and capacitor.For a stableoperation as an os- cillator, the free running frequency and the duty cy- cle are both accurately controlled with two external resistors and one capacitor ...
