DESCRIPTION
The HCF4047B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4047B consist 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
RC-Common terminals.
For operating modes see functional terminal
connections and application notes.

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.
t1 = -RC In VDDVT+RVTR
t2 = -RC In 2VVDDDD--VVTTRR
t3 = 2(t1+t2)= -2RC In(VDD(V+TRV)T(VR)D(D2V- DVDTR- )VTR)
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 period may vary as a function of frequency
with respect to VDD and temperature.
MONOSTABLE WAVEFORMS
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.
t1 = -RC In 2VVTDRD
t2 = -RC In 2VVDDDD--VVTTRR
tM = (t1+t2)= -RC In (2(VVTDRD)(-VVDTDR)-(2VVTRD)D)
