DM54121
DM54121 is One-Shot with Clear and Complementary Outputs manufactured by National Semiconductor.
Description
The DM54 74121 is a monostable multivibrator featuring both positive and negative edge triggering with plementary outputs An internal 2k X timing resistor is provided for design convenience minimizing ponent 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 remendations
