... Rev 0; 6/07 1000 Base-T, ±15kV ESD Protection LAN Switch 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 outside connection ...

... A_ to _B1, LED_ to _LED1 _B2, LED_ to _LED2 Analog Signal Levels The on-resistance of the MAX4927 is very low and sta- ble as the analog input signals are swept from ground to V (see the Typical Operating Characteristics). The DD switches are bidirectional, allowing A_ and _B_ to be configured as either inputs or outputs. ± ...
