TI TS3L110DR

The TS3L110 LAN switch is a 4-bit, 2-to-1 multiplexer/demultiplexer with a single switch enable (E) input. When E is low, the switch is enabled and the I ports are connected to the Y ports. When E is high, the switch is disabled and a high-impedance state exists between the I and Y ports. The select (S) input controls the data path of the multiplexer/demultiplexer.

The TS3L110 device can be used to replace mechanical relays in LAN applications. With flat, low on-state resistance (ron), high bandwidth, and low crosstalk, this device is suitable for digital input Class D audio amplifiers in 10/100 Base-T and various other LAN applications. The TS3L110 device can be used to route signals from a 10/100 Base-T Ethernet transceiver to an RJ-45 LAN connector in a laptop or docking station. This device is designed for low channel-to-channel skew and low crosstalk.

The device is fully suitable for partial power-down applications with Ioff. The Ioff feature ensures that damaging current is prevented from back-flowing through the device when powered off. The device provides isolation when powered down.

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