About this product
The NE555 is a general-purpose timer IC widely used in astable mode as a free-running oscillator, where two resistors and one capacitor set the output frequency. It is used to generate square waves and pulses in LED flashers, clock generators, PWM circuits and timing applications.

Frequently asked questions
What is the price of NE555 Timer IC Astable Oscillator in Egypt?
NE555 Timer IC Astable Oscillator currently costs 8.5 EGP in Egypt.
Where can I buy NE555 Timer IC Astable Oscillator in Egypt?
NE555 Timer IC Astable Oscillator is available from UGE. Compare the offers above to find the best price.
How do I calculate the output frequency?
In astable mode, f ≈ 1.44 / ((R1 + 2·R2) × C), where R1 and R2 are in ohms and C is in farads. The duty cycle is (R1 + R2) / (R1 + 2·R2).
Can I run it from a 5 V supply?
Yes, 5 V is within the 4.5 V to 16 V supply range. Place a 100 nF decoupling capacitor close to the VCC and GND pins for stable operation.
