DESCRIPTI ON
TheHCC4047B (extended temperature range) and

HCF4047B (intermediate temperature range) are

monolithic integrated circuits, available in 14-lead

APPLICATION INFORMATION

1 - CIRCUIT DESCRIPTION
Astableoperation is enabled by a high level on the

ASTABLE input. The periodof thesquare wave at
the Q and Q Outputs in thismode of operation is a
function of the external components employed.
”True” inputpulseson the ASTABLEinputor ”Com­plement”pulsesontheASTABLEinputallowthe cir­cuit to be used as a gatable multivibrator. The
OSCILLATORoutputperiodwillbehalf of theQter­minaloutput in the astable mode. However, a 50%
duty cycle is not guaranteed at this output. In the
monostable mode, positive-edge triggering is ac­complished by application of a leading-edge pulse
to the +TRIGGERinput and a low levelto the –TRI­GGER input. For negative-edge triggering, a trail­ing-edge pulse is applied to the –TRIGGER and a
highlevelis applied tothe+TRIGGER.Input pulses
may be of any duration relative to the outputpulse.
The multivibratorcan be retriggered (on the leading
edge only) by applying a common pulse to both the
RETRIGGERand +TRIGGER inputs. In this mode

Minimum Output High (source) Current Charac­teristics.

the output pulse remains high as long as the input
pulse period is shorter than the period determined
by theRC components. An external countdown op­tion can be implementedby coupling ”Q” to an ex­ternal”N” counter andresettingthecounter with the
trigger pulse. The counter output pulse is fed back
to the ASTABLE input and has a duration equal to
N times the period of the multivibrator. A high level
on the EXTERNAL RESETinputassures no output
pulse during an ”ON” power condition. This input
can also be activated to terminate the output pulse
at anytime. Inthemonostable mode, a high-level or
power-on reset pulse, must be applied to the EX­TERNALRESET whenever VDDis applied.

ationsfromunit-to-unit asafunctionoftransfer-volt­age (VTR) shift (33% – 67% VDD) for free-running

of external counting circuitry. Advantages include
digitallycontrolledpulseduration,smalltimingcapa­citors for long time periods, and extremely fast re­coverytime.

Figure B : Implementation of External Counter Option.

6 - POWER CONSUMPTION
In the standby mode (Monostable or Astable),

power dissipation will be a function of leakage cur­rent in the circuit, as shown in the static electrical
characteristics. For dynamic operation, the power
needed to charge the external timing capacitor C is
givenby the following formula :

AstableMode : P = 2CV2f. (Outputat Pin 13)

P= 4CV2f. (OutputatPin10and11)

Monostable Mode : P=

(2.9CV2) (Duty Cycle)

(Output at Pin 10 and 11)

power is consumed in the externalcomponents. In
practice,the lowerthe valuesof frequency and volt-

be to the calculated value.

Becausethe powerdissipationdoes notdepend on
R, adesignforminimum power dissipationwouldbe
a smallvalue of C.The valueofR woulddepend on
the desired period (within the limitations discussed
above).

7 - TIMING-COMPONENTLIMITATIONS
The capacitor used in the circuit shouldbe non-po-

larized andhavelowleakage(i.e.theparallel resist­ance of the capacitor should be an order of
magnitude greater than the external resistorused).

However, in consideration of accuracy, C must be
much larger than the inherent stray capacitance in

the system (unless this capacitance can be
measured andtakenintoaccount). R must bemuch
largerthan the COS/MOS”ON” resistance inseries
with it,which typically is hundreds of ohms. In addi­tion,with verylarge valuesof R, some short-term in­stability with respectto time may be noted.

C ≥ 100pF, up to any practical value, for astable
modes;

C ≥ 1000pF, up to any practical value, for mono­stable modes.

10KΩ ≤ R ≤ 1MΩ.
