NSC CD4047 Low power monostable/astable multivibrator Datasheet

CD4047BM/CD4047BC Low Power
Monostable/Astable Multivibrator
General Description
CD4047B is capable of operating in either the monostable
or astable mode. It requires an external capacitor (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 frequency
(at 50% duty cycle) at Q and Q outputs is determined 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 triggered by low-to-high transition at a trigger input or high-tolow transition at b trigger input. The device can be retriggered by applying a simultaneous low-to-high transition to
both the a trigger and retrigger inputs.
A high level on Reset input resets the outputs Q to low, Q to
high.
