DC ELECTRICAL CHARACTERISTICS

Note 1.

Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is

not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng

conditions for extended periods may affect device reliability.

Note 2.

The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

Note 3.

Measured with die attach pad soldered to PCB, JEDEC standard multi-layer board.
