4.4 MTBF
Mean Time Between Failures (MTBF) is predicted based on reliability data for the individual components
in this device. The measurement assumes that device failure rate can be generated by the sum of failure
rates in each component and a steady state failure rate can be predicated as equal to or greater than
4.20 x 10
6
hours.
Notes about the MTBF:
The MTBF is predicated and calculated based on “Bellcore Analysis Method 1”.

Caution: Absolute Maximum Stress RatingsApplied conditions greater than those listed under
“Absolute Maximum Stress Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these conditions or conditions greater than those defined in
the operational sections of this data sheet is not implied. Exposure to absolute maximum stress rating
conditions may affect device reliability.
