M602 Ding Dong Doorbell IC

This IC was the heart of millions of doorbells all around the world, but it has become scarce in recent years. We just bought a large quantity of these ICs and so here they are.

These ICs are very easy to use and require just a few extra components. Datasheet is here.

Note, we are even doing a doorbell kit using them, if you would rather everything is supplied.
