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

HIGH-to-LOW transition at

be retriggered by applying a simultaneous LOW-to-HIGH

transition to both the

A high level on Reset input resets the outputs Q to LOW, Q

to HIGH.
