Important Note:

All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually performed during

production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test equipment, specifically the LTX77

Series system. Unless otherwise noted, all tests are pulsed tests, therefor TJ = TC = TA.

Test Level

Test Procedure

100% production tested and QA sample tested per QA test plan QCX0002.

100% production tested at TA = 25°C and QA sample tested at TA = 25°C, TMAX and TMIN per QA test plan QCX0002.

III

QA sample tested per QA test plan QCX0002.

Parameter is guaranteed (but not tested) by Design and Characterization Data.

Parameter is typical value at TA = 25°C for information purposes only.
