CD4047BMS December 1992 CMOS Low-Power Monostable/Astable Multivibrator Description CD4047BMS consists of a gatable astable multivibrator with logic techniques incorporated to permit positive or negative edge triggered 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 RCCommon terminals. Astable operation is enabled by a high level on the ASTABLE input or a low level on the ASTABLE input, or both. 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. The CD4047BMS triggers in the monostable mode when a positive going edge occurs on the +TRIGGER input while the -TRIGGER is held low. Input pulses may be of any duration relative to the output pulse. If retrigger capability is desired, the RETRIGGER input is pulsed. The retriggerable mode of operation is limited to positive going edge. The CD4047BMS will retrigger as long as the RETRIGGER input is high, with or without transitions (See Figure 31) An external countdown option can be implemented by coupling “Q” to an external “N” counter and resetting the counter with 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. For monostable operation, whenever VDD is applied, an internal power on reset circuit will clock the Q output low within one output period (tM). The CD4047BMS is supplied in these 14-lead outline packages: Braze Seal DIP H4Q Frit Seal DIP H1B Ceramic Flatpack H3W Features • High Voltage Type (20V Rating) • Low Power Consumption: Special CMOS Oscillator Configuration • Monostable (One-Shot) or Astable (Free-Running) Operation • True and Complemented Buffered Outputs • Only One External R and C Required • Buffered Inputs • 100% Tested for Quiescent Current at 20V • Standardized, Symmetrical Output Characteristics • 5V, 10V and 15V Parametric Ratings • Meets All Requirements of JEDEC Tentative Standard No. 13B, “Standard Specifications for Description of ‘B’ Series CMOS Devices” Monostable Multivibrator Features • Positive or Negative Edge Trigger • Output Pulse Width Independent of Trigger Pulse Duration • Retriggerable Option for Pulse Width Expansion • Internal Power-On Reset Circuit • 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% Astable Multivibrator Features • Free-Running or Gatable Operating Modes • 50% Duty Cycle • Oscillator Output Available • Good Astable Frequency Stability: Frequency Deviation: - = ±2% + 0.03%/oC at 100kHz - = ±0.5% + 0.015%/oC at 10kHz (Circuits “Trimmed” to Frequency VDD = 10V ± 10% Pinout C1 R2 R-C COMMON 3 ASTABLE 4 ASTABLE 5 -TRIGGER 6 VSS 7 CD4047BMS TOP VIEW 14 VDD 13 OSC OUT 12 RETRIGGER 11 Q 10 Q 9 EXT.

TERMINAL 13 t1 t2 t1 t2 Monostable Mode Design Information The following analysis presents variations from unit to unit as a function of transfer voltage (VTR) shift (33% - 67% VDD) for one shot (monostable) operation.

ASTABLE MODE WAVEFORMS VTR ; VDD + VTR typically, t1 = 1.1RC VDD - VTR ; 2VDD - VTR typically, t2 = 1.1RC FIGURE 30. MONOSTABLE WAVEFORMS VTR ; 2VDD typically, t1´ = 1.38RC t1 = -RC In t1´ = -RC In tM = (t1´ + t2) tM = -RC In (VTR)(VDD - VTR) (2VDD - VTR)(2VDD) t2 = -RC In tA = 2(t1 + t2) = -2RC In (VTR)(VDD - VTR) (VDD + VTR)(2VDD - VTR) tA = 4.40RC tA = 4.62RC tA = 4.62RC where tM = Monostable mode pulse width. Values for tM are as follows: Typ: VTR = 0.5VDD Min: VTR = 0.33VDD Max: VTR = 0.67VDD tM = 2.48RC tM = 2.71RC tM = 2.48RC Typ: VTR = 0.5VDD Min: VTR = 0.33VDD Max: VTR = 0.67VDD thus if tM = 2.48RC is used, the variation will be +9.3%, -0% due to variations in transfer voltage. NOTES: 1. In the astable mode, the first positive half cycle has a duration of tM; succeeding durations are tA/s. 2. In addition to variations from unit to unit, the monostable pulse width varies with VDD and temperature. These variations are presented in graphical form in Figures 19 to 26 with 10V as reference for voltage variation curves and +25oC as reference for temperature variation curves. thus if tA = 4.40RC is used, the variation will be +5%, -0% due to variations in transfer voltage. Variations Due to VDD and Temperature Changes In addition to variations from unit to unit, the astable period varies with VDD and temperature, Typical variations are presented in graphical form in Figures 11 to 18 with 10V as reference for voltage variations curves and +25oC as reference for temperature variations curves. 7-909 CD4047BMS Retrigger Mode Operation The CD4047BMS can be used in the retrigger 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 terminal 12, and the output is taken from terminal 10 or 11. As shown in Figure 31 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, the output pulse width is an integral number of time periods, with the first time period being t1´ + t2, typically, 2.48RC, and all subsequent time periods being t1 + t2, typically, 2.2RC. However, in consideration of accuracy, C must be much larger than the inherent stray capacitance in the system (unless this capacitance can be measured and taken into account). R must be much larger than the CMOS “ON” resistance in series with it, which typically is hundreds of Ω. In addition, with very large values of R, some short term instability with respect to time may be noted. The recommended values for these components to maintain agreement with previously calculated formulas without trimming should be: C ≥ 100pF, up to any practical value, for astable modes; C ≥ 1000pF, up to any practical value for monostable modes. 10kΩ ≤ R ≤ 1MΩ 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 Figure 32. The pulse duration at the output is text = (N - 1) (tA) + (tM + tA/2) where text = pulse duration of the circuitry, and N is the number of counts used. 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 terminal No. 13) AST CD4047BMS Q INPUT PULSE CL CD4017BMS R 11 12 OPTIONAL BUFFER OUT P = 4CV2f. (Output at terminal Nos. 10 and 11) Monostable Mode: P= (2.9CV2) (Duty Cycle) T TEXT (Output at terminal Nos. 10 to 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 voltage 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). See Figures 26, 27, and 28 for typical power consumption in astable mode. FIGURE 32. IMPLEMENTATION OF EXTERNAL COUNTER OPTION 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 at least an order of magnitude greater than the external resistor used). There is no upper or lower limit for either R or C value to maintain oscillation. +TRIGGER & RETRIGGER TERMINALS 8 & 12 OSC OUTPUT TERMINAL 13 t1´ t2 t1´ t2 t1´ t2 t1´ t2 t1´ t2 t1´ t2 t1´ t2 t1´ t2 t1´ t2 t1´ t2 Q OUTPUT TERMINAL 10 tRE tRE tRE tRE FIGURE 31.
