DM54123, DM74123
Dual Retriggerable One-Shot with Clear and Complementary Outputs
The ‘123 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. A low at the clear (CLR)
input terminates the output pulse: which also inhibits triggering. An internal connection from CLR to
the input gate makes it possible to trigger the circuit by a positive-going signal on the CLR.
