Overview
The TS3L301DGGR 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-performance switching applications, particularly in local area networks (LANs), including 10/100/1000 Base-T Ethernet signaling. It features a single select (SEL) input that controls the data path of the multiplexer/demultiplexer, making it versatile for various signal routing tasks.
