DESCRIPTION
The HCC4047B (extended temperature range) and
HCF4047B (intermediate temperature range) are
monolithic integrated circuits, available in 14-lead
dual in-line plastic or ceramic package and plas-
tic micropackage. The HCC/HCF4047B consists of
a gatable astable multivibrator with logic techniques
incorporated to permit positive or negative edge-
triggered monostable multivibrator action with retrig-
gering and external counting options. Inputs include
+TRIGGER -TRIGGER, ASTABLE, ASTABLE, RE-
TRIGGER, and EXTERNAL RESET. Buffered out-
puts are Q, Q, and OSCILLATOR. In all modes of
operation, an external capacitor must be connected
between C-Timing and RC-Common terminals, and
an external resistor must be connected between the
R-Timing and RC-Common terminals. For operating
modes see functional terminal connections and ap-
plication notes.
