KK74123
Dual Monostable Multivibrator with Clear
The KK74123 multivibrator feature d-c triggering from gated lowlevel-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.
