SEQUENTIAL_TIMER_1

Published:2009/6/29 2:21:00 Author:May | From:SeekIC

By utilizing both halves of a dual timer it is possible to obtain sequential timing. By connecting the output of the first half to the input of the second half via a.001μF coupling capacitor sequential timing may be obtained. Delay t1 is determined by the first half and t2 by the second half delay. The first halfof the timer is started by momentarily connecting pin 6 to ground. When it is turned out (determined by 1.1R1C1), the second half begins. Its duration is determined by 1.1R2C2.
