DESCRIPTION/ORDERING INFORMATION
The TS2PCIE2212 can be used to muxltiplex/demultiplex two PCI Express™ lanes, each representing
differential pairs of receive (RX) and transmit (TX) signals. The switch operates at the PCI Express bandwidth
standard of 2.5-Gbps signal-processing speed. The device is composed of two banks, with each bank
accommodating two sources (source A and source B) and two destinations (destination A and destination B).
When a logic-level low is applied to the control (CTRL) pin, source A is connected to destination A and source B
is connected to destination B. When a logic-level high is applied to CTRL, source A is connected to destination
B, while source B and destination A are open.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages are with respect to ground, unless otherwise specified.
The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
VI and VO are used to denote specific conditions for VI/O.
II and IO are used to denote specific conditions for II/O.
The package thermal impedance is calculated in accordance with JESD 51-7.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
