NE556

The NE556 IC is the dual version of NE555 IC, meaning the NE556 has two timers inside it. As we know 555 ICs have been used for a long time now due to their reliable properties and applications. The NE556 can also be used for all those application additionally since this works with CMOS technology we can have two timers inside a single package with improved characteristics.
