1.8 V configurable registered buffer for DDR2-667 RDIMM applications
8.
Limiting values
[1]
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
[2]
This value is limited to 2.5 V maximum.
9.
Recommended operating conditions
[1]
The RESET and Cn inputs of the device must be held at valid logic levels (not floating) to ensure proper device operation.
[2]
The differential inputs must not be floating, unless RESET is LOW.
Table 4:
In accordance with the Absolute Maximum Rating System (IEC 60134).
