Working Principles

The NE556V is a dual precision timer integrated circuit that combines two independent 555 timers in a single package. It operates by using external resistors and capacitors to control the timing functions. The trigger input (TRIG) initiates the timing cycle, while the threshold input (THRES) determines when the output switches state. The control voltage input (CONT) allows for modulation of the timing characteristics. The discharge output (DISCH) discharges the timing capacitor, and the reset input (RESET) resets the timing cycle.
