What is the maximum supply voltage for a LM555?
The 555 timer can be used with a supply voltage (Vs) in the range 4.5V to 15V (18V is the absolute maximum).
How many pins is LM555?
Pinout. The pinout of the 8-pin 555 timer and 14-pin 556 dual timer are shown in the following table.
What is the output voltage of a 555 timer?
The standard TTL 555 can operate from a supply voltage between 4.5 volts and 18 volts, with its output voltage approximately 2 volts lower than its supply voltage VCC. The 555 can source or sink a maximum output current of 200mA, (but it may get hot at this level), so the circuit variations are unlimited.
What is the difference between NE555 and lm555?
Is NE555 same as lm555? They’re the same thing. Just “555” refers to the generic concept of a 555 timer IC. The NE555 was the original part number assigned by Signetics to the commercial temperature range variant (SE555 was the military temperature range type).
How do you set a 555 timer?

How can you check 555 IC timer?
How to Check the 555 Timer IC? First of all, insert the IC in socket (if used) very carefully so that no pin of 555 timer gets damage. Now to see the result, switch on the power supply. If your 555 timer is working properly, then both the LEDs (Red LEDs in my case) will glow alternately.
Are all 555 chips the same?
Due to minor variations in process the CMOS chips can have variations in performances and speeds, but mostly they are interchangeable with each other, just like a standard 555 is usually interchangeable between manufacturers.
Why IC 555 is called Timer?
The 555 Timers name comes from the fact that there are three 5kΩ resistors connected together internally producing a voltage divider network between the supply voltage at pin 8 and ground at pin 1.
