Time from microseconds through hours with Jameco's selection of Standard 555 IC timers. Our huge variety of standard timers with 8-pins includes: plastic dip rail, SOIC N rail, MDIP rail, and more. A highly stable device for generating accurate time delays or oscillation, the LM555 features additional terminals for triggering or resetting if desired.
Standard 555 IC Timer Single 8-Pin MDIP
The LM555 is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free running frequency and duty cycle are accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output circuit can source or sink up to 200mA or drive TTL circuits. Direct replacement for SE555/NE555.
