<strong>CD4047BM</strong><strong>CD4047BC</strong> <strong>Low</strong> <strong>Power</strong><br />
<strong>Monostable</strong><strong>Astable</strong> <strong>Multivibrator</strong><br />
General Description<br />
CD4047B is capable of operating in either the monostable<br />
or astable mode It requires an external capacitor (between<br />
pins 1 and 3) and an external resistor (between pins 2 and<br />
3) to determine the output pulse width in the monostable<br />
mode and the output frequency in the astable mode<br />
October 1993<br />
MONOSTABLE MULTIVIBRATOR FEATURES<br />
Y Positive- or negative-edge trigger<br />
Y Output pulse width independent of trigger pulse duration<br />
Y Retriggerable option for pulse width expansion<br />
Y Long pulse widths possible using small RC components<br />
by means of external counter provision<br />
<strong>Astable</strong> operation is enabled by a high level on the astable<br />
Y<br />
input or low level on the astable input The output frequency Fast recovery time essentially independent of pulse<br />
(at 50% duty cycle) at Q and Q outputs is determined by the<br />
width<br />
Y<br />
timing components A frequency twice that of Q is available Pulse-width accuracy maintained at duty cycles approaching<br />
100%<br />
at the Oscillator Output a 50% duty cycle is not guaranteed<br />
<strong>Monostable</strong> operation is obtained when the device is triggered<br />
by low-to-high transition at a trigger input or high-to-<br />
Y Free-running or gatable operating modes<br />
ASTABLE MULTIVIBRATOR FEATURES<br />
low transition at b trigger input The device can be retriggered<br />
by applying a simultaneous low-to-high transition to<br />
Y 50% duty cycle<br />
Y Oscillator output available<br />
both the a trigger and retrigger inputs<br />
Y Good astable frequency stability<br />
A high level on Reset input resets the outputs Q to low Q to typical e g2% a 003%C 100 kHz<br />
