[Precautions for light]

Due to the solar battery principle, the characteristics of the semiconductor devices generally change when

the devices are irradiated. This IC, therefore, may malfunction when exposed to light.

Since this IC is not completely lightproof, follow the precautions below when using a substrate or product

on which it is mounted.

(1) Design and mount the substrate or product so as to block out any light from reaching the IC during

actual use.

(2) For the inspection process, design the environments so as to block out any light from reaching the

IC.

(3) When blocking out light, take all surfaces of the IC chip into account.
