- Not is easier than this. Thake a dual-monoflopp from the cmos-family
- MC14xxx (MOTOROLA) or CD4xxx (NATIONAL SEMIC. or Second Source).
- There are two types of monoflopps, MC14528B or MC14538B. The first
- device is for smaller min. pulse. The second device is more stable and
- the pulse-width is exactly r*c.

- For more information: Have a look in the databook CMOS LOGIC DATA (MOTOROLA)

- I hope I can help you. Greetimg from Thomas
