Part Number: LM555 Hi,
the LM555 timer is designed as VCO with input control voltage to receive certain frequency, but the formula which is given in the datasheet doesn't applicable with this design (there control voltage is grounded).
so, could…
Part Number: LM555 I am using this IC in my design. For understanding I want to know the output of flip flop which is Q or Qbar in internal circuit. I have checked in datasheet it is not given. So, kindly confirm the output of RS flipflop.
Part Number: LM555 Other Parts Discussed in Thread: TLC555 Hi team,
My customer want a time delay device.

Part Number: LM555 Other Parts Discussed in Thread: NE555 Hi experts,
Could you help me check what is the main difference between LM555 and NE555?
At the same time, compared with our two devices, which one do we mainly recommend customers to use? These…
Part Number: LM555 Other Parts Discussed in Thread: TLC555 Dear Team,
Out customer need RC timer solution: similar with 555 oscillator.
Vcc 12V
Frequency: 50HZ~60HZ
operating temp : -40~+105
Please advise. Thanks.
Many Thanks,
Jimmy
Hello,
I appreciate all your efforts! Unfortunately non of the provided solutions worked for me. However, after a lot of experimenting, using an open collector-collector circuit connected to the trigger pin on LM555 and PIC microcontroller did the job…
Part Number: LM555 Dear Sir.
I tested the circuit below.
The load is a filament heater with 3.3Ohm,
but the LM555 timer was sometimes dead and LED was burnt.
Could you check what is problem with this circit ?
Best Regards,Yoon.
Part Number: LM555 Hi Team, May I ask for your help? Kindly see customer concern below: " At this moment everything is highly conceptual, what we are needing is a timer that can perform the speeds of a photographic shutter. We are very interested in…
Part Number: LM555 Hi Team,
Our customer is designing a push-pull converter and they intend to use the LM555, but it will with no feedback and no dead time. Would this be suitable for this use case? Are there any potential risks of having open-loop and…
