Overview
The TS3L301 is a 16-bit to 8-bit Single-Pole Double-Throw (SPDT) gigabit LAN switch produced by Texas Instruments. This device is designed for high-speed data switching applications, particularly in local area networks (LANs). It features a single select (SEL) input that controls the data path of the multiplexer/demultiplexer, making it suitable for various LAN applications such as 10/100/1000 Base-T Ethernet signaling.
