SSTUB32864

1.8 V configurable registered buffer for DDR2-800 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.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134).
