description/ordering information (continued)
This device can be used to replace mechanical relays in LAN applications. This device has low and flat r
on
, wide
bandwidth, and low crosstalk, making it suitable for 10 Base-T, 100 Base-T, and various other LAN applications.
The device can be used to route signals from a 10/100 Base-T ethernet transceiver to the RJ-45 LAN connectors
in laptops or in docking stations. The device is designed for low channel-to-channel skew and low crosstalk.
This device is fully specified for partial-power-down applications using I
off
. The I
off
feature ensures that
damaging current will not backflow through the device when it is powered down. The device has isolation during
power off.
To ensure the high-impedance state during power up or power down, E should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
