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:

I found that the NE555S-13 is featured in the [Falstad web simulator.](https://www.falstad.com/circuit/)

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 volts 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 configurations I saw seemingly similar results in the wave generation.

Is there something I am not seeing?
