74121  MONOSTABLE MULTIVIBRATORS WITH SCHMITT-TRIGGER INPUTS

DM74121
One-Shot with Clear and Complementary Outputs
General Description
The DM74121 is a monostable multivibrator featuring both
positive and negative edge triggering with complementary
outputs. An internal 2kΩ 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 and active-HIGH transition Schmitttrigger 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 one-shot application notes carefully
and observe recommendations
