Monostable multivibrator generates a precise output pulse of defined width when triggered. Pulse width = 0.45 x Rext x Cext. Retriggerable: new trigger during output pulse extends the pulse. Direct reset (CLR) terminates output pulse immediately. Edge-triggered from A (falling) or B (rising) inputs.<\/p>\n
