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.

Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested.
3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The
time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of
typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is
determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
