CD4047BM/CD4047BC Low Power

Monostable/Astable Multivibrator

MONOSTABLE MULTIVIBRATOR FEATURES

General Description

Positive- or negative-edge trigger

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.

Output pulse width independent of trigger pulse dura-

tion

Retriggerable option for pulse width expansion

Long pulse widths possible using small RC components

by means of external counter provision

Fast recovery time essentially independent of pulse

width

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.

Pulse-width accuracy maintained at duty cycles ap-

proaching 100%

Monostable operation is obtained when the device is trig-

gered by low-to-high transition at

trigger input or high-to-

trigger and retrigger inputs.

Good astable frequency stability

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

high.
