USAGE PRECAUTIONS

Printed circuit board ground lines should be set up with consideration for common impedance.

Take appropriate static electricity measures.

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 personal should be grounded with resistance of 250 kΩ to 1 MΩ between body and ground.

Do not apply negative voltages

The use of negative voltages below -0.3V may create parasitic transistors on LSI lines, Which can cause abnormal operation.
