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 plas- tic micropackage. TheHCC/HCF4047B consists of a gatable astable multivibrator with logic techniques incorporated to permit positive or negative edge- triggered monostable multivibrator action withretrig- gering and external counting options. Inputs include +TRIGGER -TRIGGER, ASTABLE, ASTABLE, RE- TRIGGER, and EXTERNAL RESET. Buffered out- puts 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 ap- plication notes.

APPLICATION INFORMATION
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 ”Com- plement” pulses on the ASTABLE input allow the cir- cuit to be used as a gatable multivibrator. The OSCILLATOR output period will be half of the Q ter- minal output in the astable mode. However, a 50% duty cycle is not guaranteed at this output. In the monostable mode, positive-edge triggering is ac- complished by application of a leading-edge pulse to the +TRIGGERinput and a low level to the –TRI- GGER input. For negative-edge triggering, a trail- ing-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 op- tion can be implemented by coupling ”Q” to an ex- ternal ”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 EX- TERNAL RESET whenever V DD is applied. 2 - ASTABLE MODE The following analysis presents worst-case vari- ations from unit-to-unit as a function of transfer-volt- age (V TR) shift (33% – 67% VDD ) for free-running (astable) operation. HCC/HCF4047B
t1 = – RC In VDD +V TR VDD –V TR t2 = – RC In 2V DD –V TR (VTR )( VDD –V TR )tA =2( t1 +t2) = –2 RC In(VDD +V TR )( 2VDD –V TR ) ASTABLE MODE WAVEFORMS. 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 vari- ation will be (+ 5.0%, – 0.0%) In addition to variations from unit-to-unit, the astable period may vary as a function of frequency with re- spect to VDD and temperature. 3 - MONOSTABLE MODE The following analysis presents worst-case vari- ations from unit-to-unit as a function of transfer-volt- age (VTR) shift (33% – 67% VDD ) for one-shot (monostable) operation. VTR t1 = – RC In 2V DD VDD –V TR t2 = – RC In 2V DD –V TR (VTR )( VDD –V TR )tM =( t1 +t2)=–R CI n (2 VDD –V TR )( 2VDD ) MONOSTABLE WAVEFORMS. 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 vari- ation will be (+ 9.3%, – 0.0%). Note : In the astable mode, the first positive half cycle has a duration of TM ; succeeding dur- ations are tA/2. In addition to variations from unit to unit, the mono- stable pulse width may vary as a function of fre- quency with respect to VDD and temperature. 4 - RETRIGGER MODE The HCC/HCF4047B can be used in the retrigger mode to extend the output-pulse duration, orto com- pare 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 re- trigger pulse is applied. Extended pulse duration is obtained when more than one pulse is applied. For two input pulses, t RE =t1’+t1 +2 t2. For more than two pulses, tRE (Q OUTPUT) terminates at some variable time tD after the termination of the last re- trigger pulse. tD is variable because tRE (Q OUT- PUT) terminates after the second positive edge of the oscillator output appears at flip-flop 4 (see logic diagram).

Advantages include digitally controlled pulseduration, small timing capa- citors for long time periods, and extremely fast re- covery time. A typical implementation is shown in fig. B. The pulse duration at the output is t ext =( N–1 )( tA )+( tM +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 cur- rent 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 = 2CV 2f. (Output at Pin 13) P = 4CV2f. (Output at Pin 10 and 11) (2.9CV2) (Duty Cycle)Monostable Mode : P = 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, adesign 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-po- larized and have low leakage (i.e. the parallel resist- ance 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 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 addi- tion, with very large values of R, some short-term in- stability with respect to time may be noted. The recommended values for these components to maintain agreement with previously calculated for- mulas without trimming should be : C ≥ 100pF, up to any practical value, for astable modes ; C ≥ 1000pF, up to any practical value, for mono- stable modes. 10KΩ ≤ R ≤ 1M Ω .
