DESCRIPTION/ORDERING INFORMATION
The TS3L4892 is a 16-bit to 8-bit multiplexer/demultiplexer LAN switch with a single select (SEL) input. SEL
controls the data path of the multiplexer/demultiplexer. The device provides additional I/Os for switching status
indicating LED signals.
The device provides a low and flat ON-state resistance (r_ON) and an excellent ON-state resistance match. Low
input/output capacitance, high bandwidth, low skew, and low crosstalk among channels make this device suitable
for various LAN applications, such as 10/100/1000 Base-T.
This device can be used to replace mechanical relays in LAN applications. It also 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.
