Notes:
1. Absolute Specifications (0°C ≤ TCASE ≤ +95°C; VDD = +1.8V ±0.1V, VDDQ = +1.8V ±0.1V)
2. Impedance measurement condition for output source dc current: VDDQ = 1.7V; VOUT = 1420mV; (VOUT-VDDQ)/Ioh must be less than 23.4 ohms for
values of VOUT between VDDQ and VDDQ-280mV. Impedance measurement condition for output sink dc current: VDDQ = 1.7V; VOUT = 280mV;
VOUT/Iol must be less than 23.4 ohms for values of VOUT between 0V and 280mV.
3. Mismatch is absolute value between pull-up and pull-dn, both are measured at same temperature and voltage.
4. Slew rate measured from VIL(AC) to VIH(AC).
5. The absolute value of the slew rate as measured from DC to DC is equal to or greater than the slew rate as measured from AC to AC. This is guaran-
teed by design and characterization.
6. This represents the step size when the OCD is near 18 ohms at nominal conditions across all process and represents only the DRAM uncertainty.

7. DRAM output slew rate specification applies to 533Mb/sec/pin, 667Mb/sec/pin, 800Mb/sec/pin, 900Mbps/sec/pin and
1000Mbps/sec/pin speed bins.
8. Timing skew due to DRAM output slew rate mis-match between DQS / DQS and associated DQs is included in tDQSQ and tQHS
specification.
