Texas Instruments NE555 Precision Timers IC (SMD Package) 50mm Cotton Tape Double Side Adhesive The detection distance of lowThe NE555 Precision Timer ICs are precision timing circuits capable of producing accurate time delays or oscillation. In the time delay or mono stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. Datasheet Features Timing from
