NE555P

NE555P is a xx555 precision timer. The device is a precision timing circuit capable of producing accurate time delays or oscillations. In time-delay or monostable operating modes, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle are controlled independently with two external resistors and a single external capacitor. Each timer has a trigger level equal to approximately one-third of the supply voltage and a threshold level equal to approximately two-thirds of the supply voltage. Typical applications include pulse-shaping circuits, missing-pulse detectors, pulse-width modulators, pulse-position modulators, sequential timers, pulse generators, frequency dividers, and industrial controls.
