<p>PURPOSE:To surely reset an external arithmetic unit at the time of power-on. CONSTITUTION:When a power source is turned on and the input voltage is boosted, the output signal of a level comparator 1 goes to the high level at the time of the boosting of the input voltage higher than a reference voltage even when the input voltage is boosted slowly or quickly, and this output signal starts a one shot multivibrator 3 as a trigger to output the pulse having the fixed interval of time and this pulse starts a one shot multivibrator 4 as a trigger and the output of the one shot multivibrator 4 is used as a pulse for reset.</p> |
