Description

The TS3L301 is a 16-bit to 8-bit multiplexer/demultiplexer local area network (LAN) switch with a single select (SEL) input. The SEL input controls the data path of the multiplexer/demultiplexer.

The device provides a low and flat ON-state resistance (ron) and an excellent ON-state resistance match. Low input/output capacitance, high-bandwidth, low skew, and low crosstalk among channels make this device suitable for various LAN applications, such as 10/100/1000 Base-T.
