• 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 this IC's pins may occur malfunction by short-circuit between pins. Especially, in
occasions like picking this IC up from low temperature tank during the evaluation. Be sure that not remain frost on this
IC'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.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII Semiconductor Corporation claims no responsibility for any and all disputes arising out of or in connection with any
infringement of the products including this IC upon patents owned by a third party.
