I want generate a 5 volt, around 55 Hz(50-60) square wave with an NE555S-13.

In the datasheet, I found the configuration for astable operation which I assume is what I want:

enter image description here screenshot from datasheet: https://www.diodes.com/assets/Datasheets/NE555_SA555_NA555.pdf

I found that the NE555S-13 is featured in the Falstad web simulator.

The problem is that in Falstad, the configuration for square generation is different and I don't know what to make of it, the main difference I see is that the "output" is pulled up to 5 voltvolts at the Vcc pin in the datasheet's example while in the Falstad simulation it's pulled up at the trigger pin.

Is there some significant difference because when I simulated both configurationconfigurations I saw seemingly similar results in the wave generation.

Is there something I am not seeing?

I found that the NE555S-13 is featured in the Falstad web simulator.

The problem is that in Falstad, the configuration for square generation is very different and I don't know what to make of it, the main difference I see is that the "output" is pulled up to 5 volt at the Vcc pin in the datasheet's example while in the Falstad simulation it's pulled up at the trigger pin.

Is there some significant difference between them andbecause when I know it's subjective but which would it be more preferablesimulated both configuration I saw seemingly similar results in the wave generation.
