ABSOLUTE MAXIMUM RATINGS
Note: Operation at above absolute maximum rating can adversely affect device reliability
DC OPERATING CONDITIONS (TA=0 to 70 oC, Voltage referenced to VSS = 0V)
Note:
1. VDDQ must not exceed the level of VDD.
2. VIL (min) is acceptable -1.5V AC pulse width with < 5ns of duration.
3. VREF is expected to be equal to 0.5*VDDQ of the transmitting device, and to track variations in the dc level of the same.
Peak to peak noise on VREF may not exceed ± 2% of the DC value.
4. VID is the magnitude of the difference between the input level on CK and the input level on /CK.
5. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temper-
ature and voltage range, for device drain to source voltages from 0.25V to 1.0V. For a given output, it represents the maximum dif-
ference between pullup and pulldown drivers due to process variation. The full variation in the ratio of the maximum to minimum
pullup and pulldown current will not exceed 1/7 for device drain to source voltages from 0.1 to 1.0.
6. VIN=0 to VDD, All other pins are not tested under VIN = 0V.
7. DQs are disabled, VOUT=0 to VDDQ
