CD4047BC
Low Power Monostable/Astable Multivibrator
General Description
The CD4047B is capable of operating in either the
monostable or astable mode. It requires an external capac-
itor (between pins 1 and 3) and an external resistor
(between pins 2 and 3) to determine the output pulse width
in the monostable mode, and the output frequency in the
astable mode.
Astable operation is enabled by a high level on the astable
input or low level on the astable input. The output fre-
quency (at 50% duty cycle) at Q and Q outputs is deter-
mined by the timing components. A frequency twice that of
Q is available at the Oscillator Output; a 50% duty cycle is
not guaranteed.
Monostable operation is obtained when the device is trig-
gered by LOW-to-HIGH transition at
+
trigger input or
HIGH-to-LOW transition at
trigger input. The device can
be retriggered by applying a simultaneous LOW-to-HIGH
transition to both the
+
trigger and retrigger inputs.
A high level on Reset input resets the outputs Q to LOW, Q
to HIGH.
