ASTABLE OPERATION
When the circuit is connectedas shown in figure 4
it triggersitselfandfree runsasamultivibrator.The
externalcapacitorchargesthrough R
A
andR
B
and
discharges through R
B
only. Thus the duty cycle
may be precisely set by the ratio of these two
resistors.
In the astable mode of operation, C charges and
dischargesbetween1/3 V
CC
and2/3 V
CC
. Asinthe
triggered mode, the charge and discharge times
and therefore frequency, are independent of the
supply voltage.
Figure5showsactualwaveformsgeneratedinthis
mode of operation.
The charge time (output HIGH)is given by :
t1 = 0.693 (R
A
+ R
B
) C
and the dischargetime (output LOW) by :
t2 = 0.693 (R
B
) C
Thus the total period T is given by :
T = t1 + t2 = 0.693 (R
A
+ 2R
