DM74121 One-Shot with Clear and Complementary Outputs June 1989 Revised November 1999 DM74121 One-Shot with Clear and Complementary Outputs General Description Features The DM74121 is a monostable multivibrator featuring bothTriggered from active-HIGH transition or active-LOW positive and negative edge triggering with complementary transition inputs outputs. An internal 2kΩ timing resistor is provided forVariable pulse width from 30 ns to 28 seconds design convenience minimizing component count and lay- Jitter free Schmitt-trigger input out problems. this device can be used with a single exter- Excellent noise immunity typically 1.2V nal capacitor. Inputs (A) are active-LOW trigger transition Stable pulse width up to 90% duty cycle inputs and input (B) is and active-HIGH transition Schmitt- trigger input that allows jitter-free triggering from inputs withTTL, DTL compatible transition rates as slow as 1 volt/second. A high immunity Compensated for V and temperature variations CC to V noise of typically 1.5V is also provided by internal CC Input clamp diodes circuitry at the input stage. To obtain optimum and trouble free operation please read operating rules and one-shot application notes carefully and observe recommendations.

There are three trigger inputs INT X X X capacitor (C ). Once triggered the output pulse width is from the device, two negative edge-triggering (A) inputs, X one positive edge Schmitt-triggering (B) input. independent of further transitions of the inputs and is func- tion of the timing components.
