AC Electrical Characteristics
(Continued)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5 kΩ in series with 100 pF. Machine model. 200Ω in series with 100 pF.
Note 3: Supply current measured at pins 1, 2, and 3. The 4.7 kΩ pull-up resistor on pin 7 is not tied to V
in this measurement.

Note 7: PCI Specifications Revision 2.1, Section 4.3.2. The response time is measured individually with
750 mV of overdrive applied to pin 2 then
600 mV of
overdrive applied to pin 3 and taking the worst number of the four measurements.
Note 8: PCI Specifications Revision 2.1, Section 4.3.2. The power failure response time is measured with a signal changing from 5V to 3V applied to pin 2 and a
3.3V DC applied to pin 3.
