General Description
The MAX4890E/MAX4892E meet the needs of high-speed
differential switching. The devices handle the needs of
Gigabit Ethernet (10/100/1000) Base-T switching as
well as LVDS and LVPECL switching. The MAX4890E/
MAX4892E provide enhanced ESD protection up to
±15kV, and excellent high-frequency response, making
the devices especially useful for interfaces that must go to
an outside connection.
Both devices provide extremely low capacitance
(CON), as well as low resistance (RON), for low-insertion
loss and very wide bandwidth. In addition to the four
pairs of DPDT switches, the MAX4892E provides LED
switching for laptop computer/docking station use.
The MAX4890E/MAX4892E are pin-for-pin equivalents
to the MAX4890/MAX4892 and can replace these
devices for those applications requiring the enhanced
ESD protection. Both devices are available in space-
saving TQFN packages and operate over the standard
-40°C to +85°C temperature range.
