Principio de funcionamiento
Each monostable channel produces a pulse of duration approximately 0.45 x Rext x Cext when triggered by a rising edge on A or falling edge on B. The retriggerable feature allows the output pulse to be extended by applying a new trigger before the current pulse expires – the output remains high for one full pulse width after the last trigger. The direct clear (CLR) input immediately terminates the output pulse regardless of timing. Unused channels should have Rext and Cext connected to prevent oscillation. The pulse width stability depends on the external component tolerances.
