Product data sheet
General description
The HEF4047B-Q100 is a retriggerable astable multivibrator that can be configured as
either a positive-edge or negative-edge triggered monostable multivibrator. The output
pulse width is programmed by selection of external components (Rt and Ct). Inputs
include clamp diodes. This enables the use of current limiting resistors to interface inputs
to voltages in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 3) and is suitable for use in automotive applications.

Functional description
The HEF4047B-Q100 consists of a gate-able astable multivibrator incorporating logic
techniques to permit positive or negative edge-triggered monostable multivibrator action
with retriggering and external counting options.
Inputs include +TRIGGER, −TRIGGER, ASTABLE, ASTABLE, RETRIGGER and MR
(master reset). Buffered outputs are O, O and OSCILLATOR OUTPUT. In all modes of
operation an external capacitor (Ct) must be connected between CTC and RCTC, and an
external resistor (Rt) must be connected between RTC and RCTC.
A HIGH level on the ASTABLE input enables astable operation. The period of the square
wave at O and O outputs is a function of the external components employed. ‘True’ input
pulses on the ASTABLE or ‘complement’ pulses on the ASTABLE input, allow the circuit
to be used as a gate-able multivibrator. The OSCILLATOR OUTPUT period is half of
the O output in the astable mode. However, a 50% duty factor is not guaranteed at this
output.
In the monostable mode, positive edge-triggering is accomplished by applying a leadingedge 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 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 count down option implements coupling O 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 MR 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 MR, whenever VDD is
applied.

11.1.2 Variations due to changes in VDD
In addition to variations from unit-to-unit, the astable period may vary as a function of
frequency with respect to VDD. Typical variations are presented graphically in Figure 7
and Figure 8 with 10 V as a reference.

In the astable mode, the first positive half cycle has a duration of tM: succeeding durations are ⁄2 tA.
Therefore if tM = 2.48 RtCt is used, the maximum variation is (+12%; -0.0%) at 10 V.

11.2.1 Retrigger mode operation
The HEF4047B-Q100 can be used in the retrigger mode to extend the output pulse
duration. It can also be used to compare the frequency of an input signal with the
frequency of the internal oscillator. In the retrigger mode, the input pulse is applied to
pins 8 and 12, and the output is taken from pin 10 or 11. Normal monostable action is
obtained when one retrigger pulse is applied (see Figure 10). 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 (output O), terminates at some variable time, tD, after the
termination of the last retrigger pulse. tD is variable because tRE (output O) terminates
after the second positive edge of the oscillator output appears at flip-flop 4.

11.2.2 External counter option
The use of external counting circuitry extends time tM by any amount. 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 11.
The pulse duration at the output is:

11.2.3 Timing component limitations
The capacitor used in the circuit should be non-polarized and have low leakage (that
is the parallel resistance of the capacitor should be an order of magnitude greater than
the external resistor used). There is no upper or lower limit for either Rt or Ct value to
maintain oscillation. However, for accuracy, Ct must be much larger than the inherent
stray capacitance in the system (unless this capacitance can be measured and taken
into account). Rt must be much larger than the LOCMOS ‘ON’ resistance in series with it,
which typically is hundreds of ohms.
The recommended values for Rt and Ct to comply with previously calculated formulae
without trimming should be:
• Ct ≥ 100 pF, up to any practical value
• 10 kΩ ≤ Rt ≤ 1 MΩ
11.2.4 Power consumption
In the standby mode (monostable or astable), power dissipation is a function of leakage
current in the circuit. For dynamic operation, the power required to charge the external
timing capacitor Ct is shown in the following formulae:

Because the power dissipation does not depend on Rt, a design for minimum power
dissipation would be a small value of Ct. The value of R would depend on the desired
period (within the limitations discussed previously). Typical power consumption in astable
mode is shown in Figure 12, Figure 13 and Figure 14.
