28-BIT CONFIGURABLE REGISTERED BUFFER FOR DDR2
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.
