Part Details:

19-0724; Rev 0; 5/07 2.5Gbps PCI Express Passive Switches MAX4888/MAX4889 General Description Features The MAX4888/MAX4889 high-speed passive switches o Single 1.65V to 3.6V Power-Supply Voltage route PCI Express® (PCIe) data between two possibledestinations. The MAX4888 is a quad single-pole/double- o Low Same-Pair Skew of 7ps throw (4 x SPDT) switch ideally suited for switching two o Low 120µA (Max) Quiescent Current half lanes of PCIe data between two destinations. TheMAX4889 is an octal single-pole/double-throw (8 x SPDT) o Supports PCIe Gen I Data Rates switch ideal for switching four half lanes of PCIe data o Flow-Through Pin Configuration for Ease of between four destinations. The MAX4888/MAX4889 fea- Layout ture a single digital control input (SEL) to switch signalpaths. o Industry-Compatible Pinout The MAX4888/MAX4889 are fully specified to operate o Lead-Free Packaging from a single 3.0V to 3.6V power supply and also oper-ate down to +1.65V. The MAX4888 is available in a 3.5mm x 5.5mm, 28-pin TQFN package. The Ordering Information/ MAX4889 is available in a 3.5mm x 9.0mm, 42-pin TQFN Selector Guide package. Both devices operate over the -40°C to +85°Ctemperature range.
