Notes:

7. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V and output loading of the specified I_OL/I_OHand 30 pF load

capacitance, as in part (a) of AC Test Load and Waveforms, unless otherwise specified.

8. See the last page of this specification for Group A subgroup testing information.

9. t_HZRtransition is measured at +200 mV from V_OLand –200 mV from V_OH. t_DVRtransition is measured at the 1.5V level. t_HWZand t_LZRtransition is measured

at ±100 mV from the steady state.

10. t_HZRand t_DVRuse capacitance loading as in part (b) of AC Test Load and Waveforms.
