50 pcs NE555 ic 555 DIP8 timer kit ham
50 x NE555 SGS-THOMSON DIP-8 Timer
* TTL COMPATIBLE TEMPERATURE STABILITY OF 0.005% PER C
The NE555 monolithic timing circuit isa highly stable controller capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.
