Product data sheet Rev. 02 — 9 March 2007 8 of 20 NXP Semiconductors SSTUA32864 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. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134).
