Fast Ethernet LAN Switch w/ Single Enable

Description

The PI3L110 is a 8- to 4-bit 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 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.

The PI3L110 is fully speciﬁ ed for partial-power-down applications

using I
