3. Precautions for use
• Absolute maximum ratings: Do not operate these ICs in excess of the absolute maximum ratings (as listed on the
data sheet). Exceeding the supply voltage rating can cause latch-up. Perform operations after confirming the detailed
operation condition in the data sheet.
• Operations with moisture on the S-25C160A pins may occur malfunction by short-circuit between pins. Especially, in
occasions like picking the S-25C160A up from low temperature tank during the evaluation. Be sure that not remain
frost on the S-25C160A’s pins to prevent malfunction by short-circuit.
Also attention should be paid in using on environment, which is easy to dew for the same reason.
