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 50 source impedance at 25oC. For accurate measurements, the input slew rate should be at least 5000V/s. Note 3: The test circuit consists of the human body model of 120pF in series with 1500. Note 4: The maximum power dissipation is a function of T J(max), JA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (T J(max) - TA)/JA. Note 5: Limits are guaranteed by testing, correlation or periodic characterization. Note 6: For M & N package, JA 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.
