DM74121 General Description

The DM54/74121 is a monostable multivibrator featuring both positive and negative edge triggering with complementary outputs. An internal 2kX timing resistor is provided for design convenience minimizing component count and layout problems. This device can be used with a single external capacitor. Inputs (A) are active-low trigger transition inputs and input (B) is an active-high transition Schmitt-trigger input that allows jitter-free triggering from inputs with transition rates as slow as 1 volt/second. A high immunity to VCC noise of typically 1.5V is also provided by internal circuitry at the input stage.
To obtain optimum and trouble free operation please read operating rules and NSC one-shot application notes carefully and observe recommendations.
