National Semiconductor LM555

This is a direct translation from their data sheet, which is Copyright 2006 National Semiconductor Corporation.

This works very similarly to the included 555, but it is not identical. It will work in any circuit, but voltages and capacitors may need to be tweaked to get identical outputs.

I tried to implement other 555s from Wikipedia and other sources, but they generally had significant errors in configuration or component values. NS schematic was right on.
