Symmetrical square wave
Just about anyone must be familiar with the NE555 by now. It is one of the most common components in do-it-yourself circuits. This IC, however, was not designed specifically to generate a clock signal, and certainly not one with a duty-cycle of 50%, although it is frequently used for that.
There are of course a number of circuit possibilities that could realise a duty ratio of 50%.
