(1) Junction temperature = ambient for +25 ° C specifications.
(2) Junction temperature = ambient at low temperature limits; junction temperature = ambient +18 ° C at high temperature limit for over
temperature specifications.
(3) Test levels: (A) 100% tested at +25 ° C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and
simulation. (C) Typical value only for information.
(4) Current is considered positive out of pin.
