Description
The MAX4928A/MAX4928B high-speed passive switches 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/double-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 operate 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.

Key Features   Applications/Uses
