General Description
The DM74LS221 is a dual monostable multivibrator with Schmitt-trigger input Each device has three inputs permitting the choice of either leading-edge or trailing-edge triggering Pin (A) is an active-low trigger transition input and pin (B) is an active-high transition Schmitt-trigger input that allows jitter free triggering for inputs with transition rates as slow as 1 volt second This provides the input with excellent noise immunity Additionally an internal latching circuit at the input stage also p...
