NOTES: (1) All other specifications are the same as the standard-grade.

(2) Junction temperature = ambient for 25

°C guaranteed specifications.

(3) Junction temperature = ambient at low temperature limit: junction temperature = ambient +20

°C at high temperature limit for over temperature

guaranteed specifications.

(4) Test Levels: (A) 100% tested at 25

°C. Over temperature limits by characterization and simulation.
