12. Usage Precaution

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 a bad effect on the reliability of the LSI.

Use the Devices within Recommended Operating Conditions

The recommended operating conditions are the recommended values that guarantee the normal operations of LSI.

The electrical ratings are guaranteed when the device is used within the recommended operating conditions and under the

conditions stated for each item.

Printed Circuit Board Ground Lines Should be Set up with Consideration for Common Impedance

Take Appropriate Measures Against Static Electricity

• Containers for semiconductor materials should have anti-static protection or be made of conductive material.

• After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.

• Work platforms, tools, and instruments should be properly grounded.

• Working personnel should be grounded with resistance of 250 k

 to 1 M in series between body and ground.

Do not Apply Negative Voltages

The use of negative voltages below

–0.3 V may create parasitic transistors on LSI lines, which can cause malfunctions.
