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
