Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
Note 2: Slew rate is measured with 50Ω source impedance at 25oC. For accurate measurements, the input slew rate should be at least
5000V/µs.
Note 3: The test circuit consists of the human body model of 120pF in series with 1500Ω.
Note 4: The maximum power dissipation is a function of T J(max), θJA and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (T J(max) - TA)/θJA.
Note 5: Limits are guaranteed by testing, correlation or periodic characterization.
Note 6: For M & N package, θJA is measured by soldering the unit directly on a printed circuit board and V - pins are connected to 2 square
inches of 2 oz copper.
