General Description
The MAX4889B/MAX4889C high-speed passive switch-
es route PCI Express (PCIe) data between two possi-
ble 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 10A (typ) source current and
a 60k
Ω (typ) internal biasing resistor to GND at the
_OUT_ terminals.
The MAX4889B/MAX4889C are fully specified to oper-
ate 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.
