The NE555P is a precision timer IC capable of producing accurate time delays or oscillation. 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.
Timing From Microseconds to Hours
Adjustable Duty Cycle
Astable or Monostable Operation
TTL-Compatible Output Can Sink or Source up to 200 mA
