Description
Pericom Semiconductor’s PI5L100 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, 100 Base-T, 100VG-AnyLAN or Token Ring. Generally, this part
can be used to replace mechanical relays in low voltage LAN
applications that have phsical layer, unshielded twisted pair media
(UTP) with either CAT 3 or CAT 5 grade cable.
To reduce insertion loss, PI5L100 is powered by a 6.2V Zener voltage.
