s USAGE PRECAUTIONS
1. Do not apply an input voltage greater than the maximum rating.
Do not input voltages greater than the maximum rating as this can cause damage to the LSI.
2. Use in accordance with the recommended operating conditions.
The electrical characteristics of the LSI are not guaranteed if the input voltage is greater than the maximum. Also,
LSI operation is unstable if the input voltage is less than the minimum. Therefore, always use in accordance with
the recommended operating conditions.
3. Use a wide ground line on the printed circuit board.
As the LSI uses a high frequency and therefore can generate high frequency noise, make the ground line as wide
as possible.
4. Take anti-static precautions.
• Use a holder for inserting the semiconductor which is anti-static or conductive.
• After mounting the device on a printed circuit board, store or transport the board in a conductive bag or
container.
• Earth work benches, tools, and measuring equipment.
• Ensure that maintenance personnel have a resistance of 250 kΩ to 1 MΩ in series between their body and earth.
