For reference: approx. V DD /2 ± 15mV.4. V IH (DC) is used as a simplified symbol for V IH.CA (DC100)5. V IL (DC) is used as a simplified symbol for V IL.CA (DC100)6. V IH (AC) is used as a simplified symbol for V IH.CA (AC175) and V IH.CA (AC150); V IH.CA (AC175) value is used when V REF + 175mV is referencedand V IH.CA (AC150) value is used when V REF + 150mV is referenced.7. V IL (AC) is used as a simplified symbol for V IL.CA (AC175) and V IL.CA (AC150); V IL.CA (AC175) value is used when V REF - 175mV is referencedand V IL.CA (AC150) value is used when V REF - 150mV is referenced.AC and DC Logic Input Levels for DQ and DM SignalsSymbolParameterDDR3-1066DDR3-1333Min Max Min MaxUnitsNotesV IH.DQ (DC100) DC input logic high V REF + 100 V DD V REF + 100 V DD mV 1V IL.DQ (DC100) DC input logic low V SS V REF - 100 V SS V REF - 100 mV 1V IH.DQ (AC175) AC input logic high V REF + 175 - - - mV 1, 2, 5V IL.DQ (AC175) AC input logic low - V REF - 175 - - mV 1, 2, 5V IH.DQ (AC150) AC input logic high V REF + 150 Note 2 V REF + 150 Note 2 mV 1, 2, 5V IL.DQ (AC150) AC input logic low Note 2 V REF - 150 Note 2 V REF - 150 mV 1, 2, 5V REFDQ (DC)Reference voltage forDQ, DM Inputs0.49*V DD 0.51*V DD 0.49*V DD 0.51*V DD V 3, 4Notes:1.
