TECHNICAL DATA
KK74123
Dual Monostable Multivibrator
with Clear
The KK74123 multivibrator feature d-c triggering from gated low-
level-active (A) and high-level-active (B) inputs, and also provide
overriding direct clear inputs. Complementary outputs are provided. The
retrigger capability simplifies the output pulse is terminated, the output
pulse may be extended. The overriding clear capability permits any output
pulse to be terminated at a predetermined time independently of the
timing components R and C. Figure 1 illustrates triggering the one-shot
with the high-level-active (B) inputs.
