The TI TS5L100 LAN switch is a 4-bit 1-of-2 multiplexer/demultiplexer with a single switch-enable (E)\ input. When E\ is low, the switch is enabled and the I port is connected to the Y port. When E\ is high, the switch is disabled and the high-impedance state exists between the I and Y ports. The select (S) input controls the data path of the multiplexer/demultiplexer.

This device can be used to replace mechanical relays in LAN applications. This device has low r_on, wide bandwidth, and low differential crosstalk, making it suitable for 10 Base-T, 100 Base-T, and various other LAN applications.

This device is fully specified for partial-power-down applications using I_off. The I_off feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.

To ensure the high-impedance state during power up or power down, E\ should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
