30_s_NONRETRIGGERABLE

With values shown, rnono IC gives delay period of 30 s after triggering by input pulse and ignores other input pulses during timing period. Delaytimein seconds is RC/3, where R is in ohms and C in farads. Delay can be reduced to as little as 10ms by reducing R to 30 kilohms and C to 1 μF. Maximumdelay is about 1 min, with 560 kilohms for R.-F. R. Shirley, Thirty-Second Timer Uses IC One-Shot, EDNIEEE Magazine, Jan. 1, 1972, p 73-74.
