Connect terminals 13 and 14 to turn on the power
a
nd finish the wiring sequence for this circuit. You’ll
notice that both LED 1 and LED 2 alternate going on
and off. By substituting different values for the
100mF capacitor you can change the speed of the
blinking.
In place of transistor multivibrators, TTL
multivibrators are becoming widely used today.
Think of some reasons why? Make notes on any
reasons you think TTL multivibrators would work
better than regular transistor multivibrators.
TTL multivibrators use much less space than
transistor multivibrators. TTL ICs also exert less
current than comparative transistor arrangements.
