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
all modes of operation an external capacitor (C
