ICSSSTUAF32868A
28-BIT CONFIGURABLE REGISTERED BUFFER FOR DDR2
COMMERCIAL TEMPERATURE GRADE
Operating Characteristics, TA = 25°C
The RESET and Cn inputs of the device must be held at valid levels (not floating) to ensure proper device operation.
The differential inputs must not be floating unless RESET is Low.
