PI3L510
3.3V, 4-Channel, 2:1, Mux/DeMux
Fast Ethernet LAN Switch w/ Single Enable
Description
The PI3L510 is a 8- to 4-Channel multiplexer/demultiplexer LAN
Switch with Hi-Z outputs. Industry leading advantages include a
propagation delay of less than 250ps, resulting from its low channel
resistance and I/O capacitance.
The device multiplexes differential outputs from a Fast Ethernet
transceiver (PHY) device to one of two corresponding B1 or B2
outputs. The switch is bidirectional and offers little or no attenuation
of the high-speed signals at the outputs. It is designed for low bit-to-
bit skew, high channel-to-channel noise isolation and is compatible
with various standards, such as 10/100 Base-T (Ethernet).
Generally, this part can be used to replace mechanical relays in
low-voltage LAN applications that interface a physical layer over
CAT 5 or CAT 6 unshielded twisted pair cable through an isolation
transformer.
