The internal diagram appears to be incorrect, https://www.555-timer-circuits.com/inside-the-555.html https://www.555-timer-circuits.com/inside-the-555.html The internal resistors should be connected to the upper comparator. Also, that diagram just seems confusing. Something like this makes more sense: https://www.theengineeringknowledge.com/wp-content/uploads/2020/09/Internal-diagram-of-a-555-integrated.jpg https://www.theengineeringknowledge.com/wp-content/uploads/2...
