NE555,SA555,SE555 PRECISION TIMERS z Timing From Microseconds to Hours z Astable or Monostable Operation z Adjustable Duty Cycle z TTL-patible Output Can Sink or Source Up To 200 mA Description/ordering information These devices are precision timing circuits 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. The threshold and trigger levels normally are two-thirds and one-third,...
