Test Circuit
Sample Application Circuit
Note 1. The output frequency characteristic for Nor Tape/High speed mode (pin 6: High, pin 15: Low) and that for Metal
Tape/Nor speed mode (pin 6: Low, pin 15: Low) are set to be the same.
2. Since the input bias current flows out of pins 1, 2 and pins 19, 20, a resistor (recommended value: 30 k
Ω to 350 kΩ,
maximum value: 500 k
Ω) must be connected a coupling capacitor in series with these pins.
3. *: A capacitor must be connected to the input to absorb a surge.
4. The electronic select switching level is approximately 1/2
× (VCC–0.9).
5. The value of the capacitor connected to pin 12 can be increased/decreased to adjust starting time ts at the time of
application of VCC.(C=100 μF, ts = 0.4 s.) If the capacitor value is made less than 47 μF, the ripple rejection will get
worse.
6. No capacitor is connected to pin 13. (Even if connected, the ripple can not be rejected.)
7. Extreme caution should be exercised when handling the IC as it is subject to dielectric breakdown.

Ω, capacitance: F)
