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 o...
