16-bit to 8-bit SPDT gigabit LAN switch with low & flat ON-state resistance

16-bit to 8-bit SPDT gigabit LAN switch with low & flat ON-state resistance - TS3L301


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.


  • Wide Bandwidth (BW = 900 MHz Typ)
  • Low Crosstalk (XTALK = -41 dB Typ)
  • Low Bit-to-Bit Skew [tsk(o) = 0.2 ns Max]
  • Low and Flat ON-State Resistance
    (ron = 4 Typ)
  • Low Input/Output Capacitance
    (CON = 10 pF Typ)
  • Rail-to-Rail Switching on Data I/O Ports
    (0 to 5 V)
  • VDD Operating Range From 3 V to 3.6 V
  • Ioff Supports Partial Power-Down-Mode Operation
  • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
  • ESD Performance Tested Per JESD 22
    • 2000-V Human-Body Model (A114-B, Class II)
    • 1000-V Charged-Device Model (C101)
  • Suitable for 10-/100-/1000-Mbit Ethernet Signaling
    • 10/100/1000 Base-T Signal Switching
    • Differential (LVDS, LVPECL) Signal Switching
    • Digital Video Signal Routing
    • Notebook Docking Signal Routing
    • Hub and Router Signal Switching
