Product specification
Monostable/astable multivibrator
HEF4047B
MSI
Astable operation is enabled by a HIGH level on the
ASTABLE input. 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 gatable multivibrator. The
OSCILLATOR OUTPUT period will be 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 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 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 can be implemented by
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 V
DD
is applied.
