General Description
The DM74LS123 is a dual retriggerable monostable multivibrator
capable of generating output pulses from a few
nano-seconds to extremely long duration up to 100% duty
cycle. Each device has three inputs permitting the choice of
either leading edge or trailing edge triggering. Pin (A) is an
active-LOW transition trigger input and pin (B) is an active-
HIGH transition trigger input. The clear (CLR) input terminates
the output pulse at a predetermined time independent
of the timing components. The clear input also serves
as a trigger input when it is pulsed with a low level pulse
transition ( ). To obtain the best trouble free operation
from this device please read the operating rules as well as
the Fairchild Semiconductor one-shot application notes
carefully and observe recommendations.
