Abstract
The NE555 timer first appeared in 1971. Although it is now well over 30 years old, many exam boards still include it in their specifications. This seems rather odd in a fast developing subject such as electronics. With an ever expanding range of new technology and devices to learn about, perhaps it is now time to relegate the 555 to the museum along with germanium transistors, valves and transistor multivibrators.
