Test levels: (A) 100% tested at +25

°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization

and simulation. (C) Typical value only for information.

(2)

Junction temperature = ambient for +25

°C specifications.

(3)

Junction temperature = ambient at low temperature limit; junction temperature = ambient +4

°C at high temperature limit for over

temperature specifications.

(4)

Current is considered positive out of node.
