One_shot_multivibrator_using_an_ECG955M_timer_oscillator_chip
One-shot multivibrator using an ECG955M timer/oscillator chip. Upon application of a negative trigger to pin 2 the flip-flop is set, which releases the short circuit across the external capacitor. This dives the output high. The photo shows the actual waveforms generated in this mode. The time that the output is high is given by t= 1.1 RA C and can be easily determined by the graph showing time delay. Applying a negative pulse to reset terminal 4 cluing the timing cycle discharges the capacitor and causes the cycle to start again. When the reset function is not used it is recommended that it be connected to supply voltage to avoid false triggering (courtesy GTE Sylvania Incorporated).
