Specifications

Recommended Operating Conditions (continued)

over operating free-air temperature range (unless otherwise noted)

(2) The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This

requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.

(3) The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH

(Power-On-Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.

(4) Logic functions and parameter values are not assured out of the range specified in the recommended operating conditions.
