Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. Note 2: Human body model: 1.5kΩ in series with 100pF. Machine model, 0Ω in series with 200pF. Note 3: The maximum power dissipation is a function of TJ(max) θJA and TA. Note 4: Guaranteed by design. Note 5: ∆RON is equal to the difference between NC1/NC2 RON or NO1/NO2 RON at a specified voltage. Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Symbolic Diagram 20077503
