Monostable/astable multivibrator  
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.  
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 VDD is applied.  
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.
