NOTE:Maximum power dissipation is based on
package heat-transfer limitations, not device power
consumption.
NOTICE:This document contains information on
products being sampled or in the initial production
phase of development. Verify with your local Intel
sales office that you have the latest datasheet
before finalizing a design.
WARNING: Stressing the device beyond the
“Absolute Maximum Ratings” may cause
permanent damage. These are stress ratings only.
Operation beyond the “Operating Conditions” is not
recommended and extended exposure beyond the
“Operating Conditions” may affect device
reliability.
