Product 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 specified for partial-power-down applications using IOFF. The IOFF feature ensures that damaging current will not backflow thoughout the device when it is powered down. The device has isolation during Power Off.
