Hello.
I'm searching IC chip that can have like switch function.
Make explain, when I put 100ns pulse, then IC chip make voltage.
But when I put 100ns pulse again, it cut off voltage.
Does there any IC chip that I explain???

If I understand you correctly, you wish to have an output toggle when a 100ns pulse is received.
I would look at a "D" flipflop.
Connect the /Q to the D input and connect your pulse to the clock input.
An ATTiny85 could be programmed to toggle an output
when receiving an input pulse.
Your 100nS pulse is rather short so it would need to be extended using an LM555 Monostable Multivibrator
Matlab Script
% LM555 one shot
R1=1000 % 1k ohm
C1 = 1e-6 % 100pF
t=1.1R1C1
fprintf('t= %.9f\n',t) % 100nS
Matlab Output
t= 0.001100000
By inserting the LM555 One Shot between you 100nS pulse and the ATTiny85 imput pin, the pulse received by the ATTiny85 input pin would be 1.1mS.
The ATTiny85 could be programmed to toggle an output pin whenever it received the input pulse.
An inverter (7404) could be used to invert your pulse.
The output of the inverter would be applied to pin 2 of the LM555.
I want to do like this that NOR monostable multivibrator. (cause need less parts)
But problem is
all square is not same.(just example. I'm not purpose to make pwm)
The reason is maybe purple line doesn't drop to almost 4.8 voltage.
So I add diode to constrain it's voltage.
Add 5v sorce.
little bit fine but not perfect.
How could I solve this problem?

(I change 5v to 4.6v but the green pulse getting longer....)
You need to explain carefully exactly what you are actually trying to do - I can't follow the fractmentary descriptions you've given so far, it all seems very confused, something about toggling and something
about a monostable, which are entirely separate functions (hence the confusion).
You need to learn how to layout circuit diagrams readably too, if you are to communicate them effectively,
as they are the language of electronics.
You need to provide more information.
First of all , what is the source of the 100nS pulse ?
What is the frequency of this pulse ? (looks like 500kHz (every 2 uS).
Where is the pulse generator in your schematic ?
What are the batteries V1 & V3 in the schematic ?
You show a "V2" (presumably the 100nS pulse generator) but do not identify what it is.
What is it ?
which is just a monostable multivibrator with t=0.7RC
R=5000
t=2uS
so your cap is not 1 nF. It is likely a very cheap ceramic with poor tolerance instead of a high quality mica.
Your cap is actually 0.571 nF (based on your waveforms).
Also, you stated you wanted a circuit that would TOGGLE with a pulse, which is not what your circuit does.
What do you really want and why ? (what are you doing?, What is the source of the 100nS pulse and
why are you using a circuit that does not toggle ?
