The T71L6808A is an octal-port 10/100Mbps dual speed Ethernet switch integrated both with an
embedded SSRAM and a 1K entries of address table. A high performance Fast Ethernet switch,
fully complies with the IEEE802.3, 802.3u and 802.3x specifications, can be implemented using the
T71L6808A with physical devices. The T71L6808A is intended for applications to stand-alone
switch for low-cost SOHO market.
