Data Sheet P14483EJ2V0DS00 11 PC1685G NOTE ON CORRECT USE (1) Observe precautions for handling because of electro-static sensitive devices. (2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired oscillation). (3) Keep the track length of the ground pins as short as possible. (4) Connect a bypass capacitor (example: 1 000 pF) to the VCC pin. RECOMMENDED SOLDERING CONDITIONS This product should be soldered under the following recommended conditions.

To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. * NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. 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 Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. M7 98. 8 |
