General Description
The MAX4927 meets the needs of high-speed differen-
tial 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-fre-
quency 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.
