3 shows the HC configured in the retriggerable mode. Briefly, the device operates as follows. (refer to Fig. 1): In the quiescent state, the external timing. information, including without limitation, this document, the specifications, the data sheets and application notes for Product and the precautions. The trigger-control circuit going HIGH simultaneously ini- tiates three events. First , the output latch goes LOW, thus taking the Q output of the HC to a HIGH.
