Most, if not all, of my 555 timers are the NE555 timer with 8 through hole pin DIP (Dual inline package), that are easy to insert in to a prototype breadboard. The following numbers are taken from the Fairchild Semiconductor LM555/NE555/SE555 datasheet:
- Supply voltage (Vcc): Min 4.5V – Max 16V
- Max power dissipation (Pd): 600mW
Pin layout below, starting top left and working counter clockwise.
- 1 – GND
- 2 – Trigger
- 3 – Output
- 4 – Reset
- 5 – Control voltage
- 6 – Threshold
- 7 – Discharge
- 8 – Vcc

When buying or using a 555 timer, or any other component for that matter, it is best to consult it’s datasheet, or other written documentation of it’s use and limitations. This skill takes a while to learn but is very rewarding once you get good. So, practice looking up datasheets! A Google search of the part name or number ie. “555 timer datasheet” will usually get you to a large number of datasheets. Try to find the specific part and manufacturer for your specific component if possible.
