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
