MAX4928BETN+-MAX4928BETN+T
DisplayPort/PCIe Passive Switches
General Description
The MAX4928A/MAX4928B high-speed passive switch-
es route PCI Express®(PCIe) data and/or DisplayPort™
signals between two possible destinations in desktop or
laptop PCs. The MAX4928A is intended to be used with
the ATX form factor desktop PCs, while the MAX4928B
is expected to be used in the BTX form factor.
The MAX4928A/MAX4928B are hex double-pole/dou-
ble-throw (6 x DPDT) switches. The MAX4928A/
MAX4928B feature a single digital control input (SEL) to
switch signal paths and a latch input (LE) that holds the
switches in a given state.
The MAX4928A/MAX4928B are fully specified to oper-
ate from a single +3.3V (typ) power supply. The
MAX4928A/MAX4928B are available in an industry
standard 5mm x 11mm, 56-pin TQFN package. Both
devices operate over the -40°C to +85°C extended
temperature range.

ELECTRICAL CHARACTERISTICS
(VDD= +3.3V ±10%, TA=TMINto TMAX, unless otherwise noted. Typical values are at VDD= +3.3V, TA= +25°C, unless otherwise
noted.) (Note 3)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
