1. Functional Description

• 2 Differential Channel, 2:1 multiplexer/demultiplexer switch for PCI Express Gen3

2. General

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.
