ABSOLUTE MAXIMUM RATINGS*
Voltage on VDD Supply Relative to VSS .... -0.5V to +4.6V
Voltage on VDDQ Supply
Relative to VSS .................................... -0.5V to +4.6V
VIN -0.5V to VDDQ + 0.5V
Storage Temperature (plastic) ........... -55C to +150C
Junction Temperature** ..................................... +150C

*Stresses greater than those listed under “Absolute
Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only, and functional
operation of the device at these or any other conditions
above those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect reliability.
**Maximum junction temperature depends upon
package type, cycle time, loading, ambient tempera-
ture and airflow. See Micron Technical Note TN-05-14
for more information.

3. MODE pin has an internal pull-up, and input leakage = ±10A.
4. The load used for VOH, VOL testing is shown in Figure 2. AC load current is higher than the shown DC values. AC I/O
curves are available upon request.
5. VDDQ should never exceed VDD. VDD and VDDQ can be connected together.
