I am trying to test this circuit from below but I a not sure which kind of capacitor should I use and how should I use it.
My question begins here, as I found two contradictory schematics, one is from ST and the other is from On Semiconductor. Although ON seems 'clear' on what to connect and where, ST makes it seem dubious. See the pictures as a reference.
ST seems to point that pin 1 and pin 15 should be only tied to one end of the capacitor while the other should be connected to the resistor in series. But on the following page it seems to indicate the contrary, in other words that pin 1 and 15 by extension should be tied to GND. Am i missing something?
In order to clarify or settle any doubts i referred to ON Semiconductor which can be seen below in the same picture from above.
However they do not seem to 'clear' my doubts regarding the correct connection of the capacitor as i am not familiar with the notation or drawing of the capacitor with one curved end. Mind somebody explain this part?
Now the second part of my question and that it includes the first one as well is that I am trying to test out this circuit.
However once again I am not sure which way should that capacitor be connected, since what I want to try out are capacitors of let's say 1uF and beyond, those seem to come as polarized varieties, like aluminum or tantalum. Wikipedia article states tantalum have low leakage and that they are good for sample and hold circuits and applications where timing is not critical. Overall what type of capacitor is recommended for both circuits?. Because I am confused on the right connections as I dont want to destroy or damage any component I would like to get that clarification first.
