CD4047BC

Low Power Monostable/Astable Multivibrator

■ True and complemented buffered outputs

General Description

The CD4047B is capable of operating in either the

■ Only one external R and C required

monostable or astable mode. It requires an external capac-

MONOSTABLE MULTIVIBRATOR FEATURES

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.

■ Positive- or negative-edge trigger

■ Output pulse width independent of trigger pulse duration

■ Retriggerable option for pulse width expansion

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.

■ Long pulse widths possible using small RC components

by means of external counter provision

■ Fast recovery time essentially independent of pulse

width

■ Pulse-width accuracy maintained at duty cycles

approaching 100%

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.

ASTABLE MULTIVIBRATOR FEATURES

■ Free-running or gatable operating modes

■ 50% duty cycle

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

to HIGH.

■ Oscillator output available

■ Good astable frequency stability

±10%)

Features

■ Wide supply voltage range: 3.0V to 15V

■ High noise immunity: 0.45 V_DD(typ.)

■ Low power TTL compatibility: Fan out of 2 driving 74L

or 1 driving 74LS
