Description of Operatin (See Timing Chart.)
When power is applied, the reset circuit operates to initialize the circuit. The reset time depends on the capacitance
value of C5 on pin 8 and no input signal is accepted while the reset circuit is operating. When the reset mode is released
and the input signal exceeds the input check level, C, R on pin 2 are charged and the pontential on pin 2 rises, thereby
causing the comparator (1) to be inverted. When the comparator (1) is inverted, pin 4 (C4) is charged and the potential
on pin 4 begins rising. When this potential exceeds the threshold voltage, the comparator (2) is inverted and the
program presence mode is memorized ; thus the potential on pin 4 is held at High level. During this period of time, the
output (pin 6) is held at High level. When the signal disappears and the comparator (1) is inverted, the output (pin 6)
turns to Low level, thereby causing the plunger to be driven.
The reset pulse is generated for a certain period of time each time power is applied, thereby causing the circuit to be
initialized.

Proper Cares in Using IC
Maximum Ratings
If the maximum ratings are exceeded, breakdown or deteroration may result. Use the IC in the range where the
maximum ratings are not exceeded.
Pin-to-pin Short and Inverted Insertion
These may cause breakdown or deterioration to occur. Be
extremely careful when mounting the IC on the board.
The voltage on pin 1 must not exceed that on pin 9.
The current flowing into pin 2 and pin 4 must not exceed
±0.5mA continuously.
The voltage on pin 8 is 2.5V max. and must not exceed that
on pin 7.
Electrolytic capacitors are used to set the recorded area
detect time and reset time. The actual time constants are 15
to 20% larger than the calculated values obtained by using
the catalon values of such capacitors. For polyester film
capacitor and tantalum electrolytic capacitor, the calculated
values hold to a fairly good approximation.
