Description

The MAX4889B/MAX4889C high-speed passive switches route PCI Express® (PCIe) data between two possible destinations in desktop or notebook PCs. The MAX4889B/MAX4889C are quad double-pole/double-throw (4 x DPDT) switches ideal for switching four half lanes of PCIe data between two destinations. The MAX4889B/MAX4889C feature a single digital control input (SEL) to switch signal paths.

The MAX4889C is intended for use in systems (e.g., SAS) where both the input and output are capacitively coupled, and provides a 10µA (typ) source current and a 60kΩ (typ) internal biasing resistor to GND at the _OUT_ terminals.

The MAX4889B/MAX4889C are fully specified to operate from a single +3.3V (typ) power supply. Both devices are available in an industry-standard 3.5mm x 9.0mm, 42-pin TQFN package. These devices operate over the -40°C to +85°C extended temperature range.
