Description
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.
Features
•A dual, highly stable one-shot
•Compensated for VCCand temperature variations
•Pin-out identical to DM74LS123 (Note 1)
•Output pulse width range from 30 ns to 70 seconds
•Hysteresis provided at (B) input for added noise immunity
•Direct reset terminates output pulse
•Triggerable from CLEAR input
•DTL, TTL compatible
•Input clamp diodes
Alternatives

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
