While the 555 oscillator IC is a very versatile device, it can also be quite tricky and solutions are not always obvious. Such is the case with this edge-triggered 555 monostable circuit. By ...

The 555 monostable circuit operation is almost identical to the astable oscillator, however the trigger input is not connected to the timing capacitor.

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function ...
