Absolute Maximum Ratings
Stresses greater than those listed may cause permanent damage to the device. This is a
stress rating only, and functional operation of the device at these or any other condi-
tions above those indicated in the operational sections of this specification is not im-
plied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.

Note:
1. V DD and V DDQ must be within 300mV of each other at all times. V DDQ must not exceed
V DD .

Notes:
1. All voltages referenced to V SS .
2. A full initialization sequence is required before proper device operation is ensured.
3. V IH,max overshoot: V IH,max = V DDQ + 2V for a pulse width ≤ 3ns, and the pulse width can-
not be greater than one- third of the cycle rate. V IL undershoot: V IL,min = –2V for a pulse
width ≤ 3ns.
4. I OUT = 4mA for full drive strength. Other drive strengths require appropriate scale.
