Notes

5. AC characteristics (except high Z) are tested using the Thevenin load shown in Figure (a). High Z characteristics are tested for all speeds using the test load

shown in Figure (c)

6. Test conditions assume signal transition time of 2.6 ns or less, timing reference levels of 1.3 V, input pulse levels of 0 to 2.6 V.

9. This parameter is guaranteed by design and is not tested.
