Functional DescriptionFunctional DescriptionFunctional DescriptionFunctional Description 2 Differential Channel, 2:1 multiplexer/demultiplexer switch for PCI Express Gen3 2. 2. GeneralGeneral 2. 2. GeneralGeneral The TC7PCI3212MT and TC7PCI3215MT are 2 differential channel, 1-2 multiplexer/demultiplexer for PCI Express Gen3 (8Gbps), or other high-speed interface applications. The An+/An- inputs is connected to the Bn+/Bn- or Cn+/Cn- outputs determined by the combination both the select input (SEL) and output enable (OE). When the output enable (OE) input is held high-level, the switches are open (high-impedance state) with regardless the state of select inputs and reducing consumption current. All inputs are equipped with protection circuits against static discharge. 3. 3. 3. 3.
