com 19-0841; Rev 0; 6/07 1000 Base-T, ±15kV ESD Protection LAN Switch General Description The MAX4927 meets the needs of high-speed differential switching, including that of Gigabit Ethernet (10/100/1000) Base-T switching as well as LVDS and LVPECL switching.
The MAX4927 provides enhanced ESD protection up to ±15kV and excellent high-frequency response, making the device especially useful for interfaces that must go to an outside connection.
The MAX4927 offers extremely low capacitance (CON), as well as low on-resistance (RON), for low-insertion loss and very wide bandwidth.
In addition to the four pairs of DPDT switches, the MAX4927 provides LED switching for laptop computer/docking station use.
The MAX4927 is pin-to-pin equivalent to the PI3L500-A and STMUX1000L.
The MAX4927 can replace either device in those applications, improving ESD protection and eliminating external ESD components.
The MAX4927 is available in a space-saving 56-pin TQFN package and operates over the extended -40°C to +85°C temperature range.
