Frequently asked questions
Can the NE555P run at 3.3 V?
No. The NE555P needs 4.5 V to 16 V. For 3.3 V circuits, use a CMOS 555 variant such as the TLC555, and check its datasheet for the supply range.
How do I set the frequency in astable mode?
Use f ≈ 1.44 / ((R1 + 2 × R2) × C), where R1 and R2 are resistors in ohms and C is the timing capacitor in farads. The result is in hertz.
