The Nx555 or Sx555 is a precision timing device for general-purpose timing applications from 10μs to hours or from < 1mHz to 100kHz. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. Maximum output sink and discharge sink current are greater for higher VCC and less for lower VCC.
