PI3L110

Pericom Semiconductor's PI3L series of logic circuits are produced using the Company's advanced sub-micron CMOS technology, achieving industry leading performance.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 PI3L110 device multiplexes differential outputs from a Fast Ethernet transceiver (PHY) device to one of two corresponding outputs. The PI3L110 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 PI3L110 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.
