Working Principles

The 74HC4538N,652 is a dual precision monostable multivibrator. It consists of two independent monostable circuits that can be triggered individually. When a trigger input signal is applied, the corresponding monostable circuit generates an output pulse with a duration determined by the external resistor and capacitor connected to it. The output pulse width can be precisely controlled using the control voltage (CV) pin. The reset input (RESET) allows for immediate termination of the output pulse.
