This publication is an uncontrolled document and is subject to change without notice. When referring to it please ensure that it is the
most up to date version and has not been superseded.
The products are not intended for use in applications where a failure or malfunction may cause loss of life, injury or damage to property.
The user must ensure that appropriate safety precautions are taken to prevent or mitigate the consequences of a product failure or
malfunction.
The products must not be touched when operating because there is a danger of electrocution or severe burning. Always use
protective safety equipment such as appropriate shields for the product and wear safety glasses. Even when disconnected any
electric charge remaining in the product must be discharged and allowed to cool before safe handling using protective gloves.
Extended exposure to conditions outside the product ratings may affect reliability leading to premature product failure. Use outside the
product ratings is likely to cause permanent damage to the product. In extreme conditions, as with all semiconductors, this may include
potentially hazardous rupture, a large current to flow or high voltage arcing, resulting in fire or explosion. Appropriate application design
and safety precautions should always be followed to protect persons and property.
Product Status & Product Ordering:
We annotate datasheets in the top right hand corner of the front page, to indicate product status if it is not yet fully approved for
production. The annotations are as follows:Target Information:
