NOTES:
1. All data sheet parameters specified to full range of VDD unless otherwise noted. All voltages are referenced to voltage applied to VSS bumps.
2. Supply voltage applied to VDD connections.
3. Supply voltage applied to VDDQ connections.
4. All power supply currents measured with outputs open or deselected.
5. All inputs are zero.
6. CMOS levels for I/Os are VIC
≤
VSS + 0.2 V or
≥
VDDQ – 0.2 V.
7. Device deselected as defined by the Clock Truth Table.
8. Although considerable latitude in the selection of the nominal dc value (i.e., rms value) of Vref is supported, the peak–to–peak ac compo-
nent superimposed on Vref may not exceed 5% of the dc component of Vref.
