„ USAGE PRECAUTION
1. Do not configure the IC over the maximum ratings.
If the IC is used over the maximum ratings, the LSI may be permanently damaged.
It is preferable for the device to normally operate within the recommended usage conditions. Usage outside
of these conditions can have an adverse effect on the reliability of the LSI.
2. Use the device within the recommended operating conditions.
The recommended values guarantee the normal LSI operation under the recommended operating conditions.
The electrical ratings are guaranteed when the device is used within the recommended operating conditions
and under the conditions stated for each item.
3. Printed circuit board ground lines should be set up with consideration for common impedance.
4. Take appropriate measures against static electricity.
y Containers for semiconductor materials should have anti-static protection or be made of conductive
material.
y After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.
y Work platforms, tools, and instruments should be properly grounded.
y Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ in serial body and ground.
5. Do not apply negative voltages.
The use of negative voltages below ─0.3 V may make the parasitic transistor activated to the LSI, and can
cause malfunctions.
