2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between collectoremitters at startup, the output transistor may enter the on state, even if the voltage is within the absolute maximum
ratings.
3. Measurement conditions of current transfer ratios (CTR), which differ according to photocoupler
Check the setting values before use, since the forward current conditions at CTR measurement differ according to
product.
When using products other than at the specified forward current, the characteristics curves may differ from the
standard curves due to CTR value variations or the like. Therefore, check the characteristics under the actual
operating conditions and thoroughly take variations or the like into consideration before use.
USAGE CAUTIONS
1. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.

5.
Renesas Electronics products are classified according to the following two quality grades: “Standard” and “High Quality”. The recommended applications
for each Renesas Electronics product depends on the product’s quality grade, as indicated below. “Standard”: Computers; office equipment; communications
equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic equipment; and
industrial robots etc. “High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-crime
systems; and safety equipment etc. Renesas Electronics products are neither intended nor authorized for use in products or systems that may pose a direct
threat to human life or bodily injury (artificial life support devices or systems, surgical implantations etc.), or may cause serious property damages (nuclear
reactor control systems, military equipment etc.). You must check the quality grade of each Renesas Electronics product before using it in a particular
application. You may not use any Renesas Electronics product for any application for which it is not intended. California Eastern Laboratories and Renesas
