s PRECAUTIONS

1. Do not apply any voltage greater than the maximum rating, or the LSI may be damaged.

2. Use the MB3788 under the recommended operating conditions.

If a voltage greater than the maximum voltage is applied, the electrical characteristics are not guaranteed; if a voltage smaller than the

minimum voltage is applied, the LSI operation will become unstable.

3. To ground the PC board, use the thickest cable possible because high frequencies are used which can easily produce high-frequency noise.

4. Connecting unused channel pin

For unused channels, the output voltage of the comparator for detecting a short-circuit must be fixed at the Low level.

5. Take measures against static electricity.

• Carry semiconductors in a conductive container or anti-static case.

• Carry the PC board in a conductive bag or container if it is stored or transported after packaging.

• Ground the workbench, and all tools and measuring instruments.

• Workers should be grounded through a resistance of 250 kΩ to 1 MΩ.
