MAX4888 Datasheet | Maxim Integrated

19-0724; Rev 0; 5/07 2.5Gbps PCI Express Passive Switches MAX4888/MAX4889 General Description The MAX4888/MAX4889 high-speed passive switches route PCI Express® (PCIe) data between two possible destinations. The MAX4888 is a quad single-pole/doublethrow (4 x SPDT) switch ideally suited for switching two half lanes of PCIe data between two destinations. The MAX4889 is an octal single-pole/double-throw (8 x SPDT) switch ideal for switching four half lanes of PCIe data between four destinations. The MAX4888/MAX4889 feature a single digital control input (SEL) to switch signal paths. The MAX4888/MAX4889 are fully specified to operate from a single 3.0V to 3.6V power supply and also operate down to +1.65V. The MAX4888 is available in a 3.5mm x 5.5mm, 28-pin TQFN package. The MAX4889 is available in a 3.5mm x 9.0mm, 42-pin TQFN package. Both devices operate over the -40°C to +85°C temperature range.
