Multivibrators FAQ

What is the function of the Schmitt-trigger inputs?

The Schmitt-trigger inputs provide noise immunity by requiring specific voltage thresholds to trigger the monostable state, ensuring clean transitions even with slow or noisy input signals.

Is the CD74HC4538M96E4 retriggerable?

Yes, the device is a retriggerable monostable multivibrator, meaning a new trigger pulse applied during the output pulse width will extend the pulse duration.
