Description
Pericom Semiconductor’s PI3L100 is a Quad 2:1 multiplexer/
demultiplexer LanSwitch with three-state outputs. This device
can be used for switching between various standards, such as 10
Base-T and 100 Base-T. Generally, this part can be used to replace
mechanical relays in low voltage LAN applications that have physical
layer, unshielded twisted pair media (UTP) with either CAT 3 or
CAT 5 grade cable.
