Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress ratingonly and functional

operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure

to absolute maximum rating conditions for external periods may affect device reliability.

(extends the output pulse one period) on the appli-

cation of each new trigger pulse. For operation in the

non-retriggerable mode, Q is connected to – TR

when leading-edge triggering (+ TR) is used or Q is

connected to + TR when trailingedge triggering (–

TR) is used. The time period (T) for this multivibrator
