General Description
The MAX4888A/MAX4889A high-speed passive switches
route PCI Express (PCIe) data between two possible
destinations. The MAX4888A is a quad single-pole/dou-
ble-throw (4 x SPDT) switch ideally suited for switching
two half lanes of PCIe data between two destinations. The
MAX4889A is an octal single-pole/double-throw (8 x
SPDT) switch ideal for switching four half lanes of PCIe
data between four destinations. The MAX4888A/
MAX4889A feature a single digital control input (SEL) to
switch signal paths.
The MAX4888A/MAX4889A are fully specified to oper-
ate from a single +3.0V to +3.6V power supply. The
MAX4888A is available in a 3.5mm x 5.5mm, 28-pin
TQFN package. The MAX4889A 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.
