<Precautions for Input Signal>

Because the ringing voltage VIG of the GND line is added to the input signals inside the hybrid IC, the greater the

through rate of input signals, the more opportunities there are to input a ringing signal at the rising or falling edge.

Particularly in cases where a capacitor is added to output pins 2, 3, 4, and 5 as shown in the figure below to suppress

electromagnetic noise, the ringing voltage increases even further due to charge/discharge of the capacitor. The ringing

voltage amplitude of this type may exceed 0.6V input Hysteresis voltage. Because the ringing signal can cause a

malfunction leading to failure due to over-current, be sure to apply input signals with the highest through rate possible.

Direct input with HC type CMOS ICs is recommended.
