Switching Characteristics
Over Recommended Operating Conditions, unless otheriwse specified (Figures 2, 3)
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 2: Derate N Package 12.1 mW/˚C, and M Package 8.5 mW/˚C above +25˚C.
Note 3: I
Note 4: Power supply (V
Note 5: AC input test waveforms for test purposes: t
Note 6: Input rise and rall times must not exceed 5 µs.
Note 7: The output slew rate, rise time, and fall time are measured from the +3.0V to the −3.0V level on the output waveform.
Note 8: C
Note 9: ESD Rating (HBM, 1.5 kΩ, 100 pF) ≥ 1.0 kV.
