1) Pullup slew rate is characterizted under the test conditions as shown in Figure 52
2) Pullup slew rate is measured between (
V
DDQ/2 – 320 mV ± 250 mV)
Pulldown slew rate is measured between (
V
DDQ/2 + 320 mV ± 250mV)
Pullup and Pulldown slew rate conditions are to be met for any pattern of data, including all outputs switching and only one
output switching.Example: For typical slew rate, DQ0 is switching.For minimum slew rate, all DQ bits are switchiung worst
case pattern. For maximum slew rate, only one DQ is switching from either high to low, or low to high the remainig DQ bits
remain the same as previous state.
3) Evaluation conditions: Typical: 25 °C (T Ambient),
V
DDQ = nominal, typical process.Minimum: 70 °C (T Ambient), VDDQ =
minimum, slow – slow process. Maximum: 0 °C (T Ambient),
V
DDQ = maximum, fast – fast process
4) Verified under typical conditions for qualification purposes.
5) TSOP II package devices only.
6) Only intended for operation up to 266 Mbps per pin.

1) 2)
1) The ratio of pullup slew rate to pulldown slew rate is specified for the same temperature and voltage, over the entire
temperature and voltage range. For a given output, it represents the maximum difference between pullup and pulldown
drivers due to process variation.
2) DQS, DM, and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times.
Signal transitions through the DC region must be monotonic
