DESCRIPTION
The HCC4047B (extended temperature range) and
HCF4047B (intermediate temperature range) are
monolithic integrated circuits, available in 14-lead
dual in-line plastic or ceramic package and plastic micropackage. The HCC/HCF4047B consists of
a gatable astable multivibrator with logic techniques
incorporated to permit positive or negative edgetriggered monostable multivibrator action with retriggering and external counting options. Inputs include
+TRIGGER -TRIGGER, ASTABLE, ASTABLE, RETRIGGER, and EXTERNAL RESET. Buffered outputs are Q, Q, and OSCILLATOR. In all modes of
operation, an external capacitor must be connected
between C-Timing and RC-Common terminals, and
an external resistor must be connected between the
R-Timing and RC-Common terminals. For operating
modes see functional terminal connections and application notes.

APPLICATION INFORMATION
1 - CIRCUIT DESCRIPTION
Astable operation is enabled by a high level on the
ASTABLE input. The period of the square wave at
the Q and Q Outputs in this mode of operation is a
function of the external components employed.
”True” input pulses on the ASTABLE input or ”Complement” pulses on the ASTABLE input allow the circuit to be used as a gatable multivibrator. The
OSCILLATOR output period will be half of the Q terminal output 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 +TRIGGER input and a low level to the –TRIGGER input. For negative-edge triggering, a trailing-edge pulse is applied to the –TRIGGER and a
high level is applied to the +TRIGGER. Input pulses
may be of any duration relative to the output pulse.
The multivibrator can be retriggered (on the leading
edge only) by applying a common pulse to both the
RETRIGGER and +TRIGGER inputs. In this mode
the output pulse remains high as long as the input
pulse period is shorter than the period determined
by the RC components. An external countdown option can be implemented by coupling ”Q” to an external ”N” counter and resetting the counter 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 RESET input assures no output
pulse during an ”ON” power condition. This input
can also be activated to terminate the output pulse
at any time. In the monostable mode, a high-level or
power-on reset pulse, must be applied to the EXTERNAL RESET whenever VDD is applied.
2 - ASTABLE MODE
The following analysis presents worst-case variations from unit-to-unit as a function of transfer-voltage (VTR) shift (33% – 67% VDD) for free-running
(astable) operation.
7/15
HCC/HCF4047B
ASTABLE MODE WAVEFORMS.
t1 = – RC In
t2 = – RC In
VTR
VDD + VTR
VDD – VTR
2 VDD – VTR
tA = 2 (t1 + t2) = –2 RC In
Typ : VTR = 0.5 VDD tA = 4.40 RC
Min : VTR = 0.33 VDD tA = 4.62 RC
Max : VTR = 0.67 VDD tA = 4.62 RC
thus if tA = 4.40 RC is used, the maximum variation will be (+ 5.0%, – 0.0%)
In addition to variations from unit-to-unit, the astable
(VTR) (VDD – VTR)
(VDD + VTR) (2 VDD – VTR)
period may vary as a function of frequency with respect to VDD and temperature.
3 - MONOSTABLE MODE
The following analysis presents worst-case variations from unit-to-unit as a function of transfer-voltage (VTR) shift (33% – 67% VDD) for one-shot
(monostable) operation.
MONOSTABLE WAVEFORMS.
t1 = – RC In
t2 = – RC In
VTR
2 VDD
VDD – VTR
2 VDD – VTR
tM = (t1 + t2) = – RC In
Where tM = monostable mode pulse width. Values
for tM are as follows :
Typ : VTR = 0.5 VDD tM = 2.48 RC
Min : VTR = 0.33 VDD tM = 2.71 RC
Max : VTR = 0.67 VDD tM = 2.48 RC
Thus if tM = 2.48 RC is used, the maximum variation will be (+ 9.3%, – 0.0%).
Note : In the astable mode, the first positive half
cycle has a duration of TM ; succeeding durations are tA/2.
In addition to variations from unit to unit, the monostable pulse width may vary as a function of frequency with respect to VDD and temperature.
4 - RETRIGGER MODE
The HCC/HCF4047B can be used in the retrigger
8/15
(VTR) (VDD – VTR)
(2 VDD – VTR) (2 VDD)
mode to extend the output-pulse duration, or to compare the frequency of an input signal with that of the
internal oscillator. In the retrigger mode the input
pulse is applied to terminals 8 and 12, and the output
is taken from terminal 10 or 11. As shown in fig. A
normal monostable action is obtained when one retrigger pulse is applied. Extended pulse duration is
obtained when more than one pulse is applied. For
two input pulses, tRE = t1’ + t1 + 2t2. For more than
two pulses, tRE (Q OUTPUT) terminates at some
variable time tD after the termination of the last retrigger pulse. tD is variable because t RE (Q OUTPUT) terminates after the second positive edge of
the oscillator output appears at flip-flop 4 (see logic
diagram).
HCC/HCF4047B
Figure A : Retrigger-mode Waveforms.
5 - EXTERNAL COUNTER OPTION
Time tM can be extended by any amount with the use
of external counting circuitry. Advantages include
digitally controlled pulse duration, small timing capacitors for long time periods, and extremely fast recovery time.
A typical implementation is shown in fig. B. The
pulse duration at the output is
t ext = (N – 1) (t A ) + (t M + t A /2)
Where text = pulse duration of the circuitry, and N is
the number of counts used.
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
given by the following formula :
Astable Mode : P = 2CV2f. (Output at Pin 13)
P = 4CV2f. (Output at Pin 10 and 11)
Monostable Mode : P =
(2.9CV2) (Duty Cycle)
T
(Output at Pin 10 and 11)
The circuit is designed so that most of the total
power is consumed in the external components. In
practice, the lower the values of frequency and volt-
age used, the closer the actual power dissipation will
be to the calculated value.
Because the power dissipation does not depend on
R, a design for minimum power dissipation would be
a small value of C. The value of R would depend on
the desired period (within the limitations discussed
above).
7 - TIMING-COMPONENT LIMITATIONS
The capacitor used in the circuit should be non-polarized and have low leakage (i.e. the parallel resistance of the capacitor should be an order of
magnitude greater than the external resistor used).
Three is no upper or lower limit for either R or C value
to maintain oscillation.
However, in consideration of accuracy, C must be
much larger than the inherent stray capacitance in
9/15
HCC/HCF4047B
the system (unless this capacitance can be
measured and taken into account). R must be much
larger than the COS/MOS ”ON” resistance in series
with it, which typically is hundreds of ohms. In addition, with very large values of R, some short-term instability with respect to 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.
The recommended values for these components to
maintain agreement with previously calculated formulas without trimming should be :
