s Usage Notes
1. Be sure to use SV_CC in the maximum potential.
Otherwise, it is likely to cause an operating error.

4. Appropriate care should be taken on the characteristics.
When changing an external circuit constant on actual use, secure an appropriate margin in consideration of charac-
teristic fluctuation of external parts and our ICs including transient characteristics as well as static ones.
5. Avoid the short-circuits between output pin and V_CC , output pin and GND (line-to-supply and line-to-ground), and
between output pins (load short-circuit). Otherwise, the IC is likely to emit smoke and break down.
6. An appropriate prior study should be done for use of dip soldering.
