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
