from a bunch of logic buffers in parallel to a specialised MOSFET driver, but [Mr. T’s Design Graveyard] is here with a surprising alternative. As it turns out, the ever-useful 555 timer chip ...

Even today, for some applications it is hard to beat the ubiquitous 555 timer IC. It is cheap ... The bistable mode really just exposes the internal flip flop. The monostable reacts to an input ...
