SLASE82A June 2015 – July 2015 HD3SS3411-Q1
The HD3SS3411-Q1 is a high-speed bi-directional passive switch in mux or demux configurations. Based on control pin SEL, the device switches one differential channels between Port B or Port C to Port A.
The HD3SS3411-Q1 is a generic analog differential passive switch that can work for any high speed interface applications as long as it is biased at a common mode voltage range of 0 V to 2 V and has differential signaling with differential amplitude up to 1800 mVpp. The device employs an adaptive tracking that ensures the channel remains unchanged for entire common mode voltage range.

|SEL = L||SEL = H|
The HD3SS3411-Q1 has two power modes, normal operating mode and shutdown mode. During shutdown mode, the device consumes very-little current to save the maximum power. The OEn control pin is used to toggle between the two modes.
HD3SS3411-Q1 consumes < 2 mW of power when operational and has a shutdown mode exercisable by the OEn pin resulting < 20 µW.
The OEn control pin selects the functional mode of HD3SS3411-Q1. To enter standby/shutdown mode, the OEn control pin is pulled high through a resistor and must remain high. For active/normal operation, the OEn control pin should be pulled low to GND or dynamically controlled to switch between H or L.
