... Philips Semiconductors Monostable/astable multivibrator DESCRIPTION The HEF4047B consists of a gatable astable multivibrator with logic techniques incorporated to permit positive or negative edge-triggered monostable multivibrator action with retriggering and external counting options. Inputs include + TRIGGER, TRIGGER, ASTABLE, ASTABLE, RETRIGGER and MR (Master Reset). Buffered outputs are O, O and OSCILLATOR OUTPUT. In ...

... Monostable/astable multivibrator 3. Retrigger mode operation The HEF4047B can be used in the retrigger mode to extend the output pulse duration compare the frequency of an input signal with that of the internal oscillator. In the retrigger mode the input pulse is applied to pins 8 and 12, and the output is taken from pin 10 or 11. Normal monostable action is obtained when one retrigger pulse is applied (Fig.8). ...
