1. Absolute specifications: 0°C ≤ T
2. Impedance measurement conditions for output source DC current: VddQ = 1.7V;
3. Mismatch is an absolute value between pull-up and pull-down; both are measured at
4. Output slew rate for falling and rising edges is measured between Vtt - 250mV and

6. IT and AT devices require an additional 0.4 V/ns in the MAX limit when T
Vout = 1,420mV; (Vout - VddQ)/Ioh must be less than 23.4Ω for values of Vout between
VddQ and VddQ - 280mV. The impedance measurement condition for output sink DC

rate is measured between DQS - DQS# = –500mV and DQS# - DQS = +500mV. Output
slew rate is guaranteed by design but is not necessarily tested on each device.
