The XR31234 is a controller area network (CAN) transceiver that conforms to the ISO 11898 standard. It provides transmit and receive signaling rates up to 1Mbps between a differential CAN bus and a CAN controller.
This device is designed with cross-wire protection, overvoltage protection up to ±36V, loss of ground protection, thermal shutdown protection and common-mode transient protection of ±100V making it ideal for harsh environments used in industrial, automotive, transportation and building automation applications.
The low power consumption of the 3.3V supply makes the XR31234 CAN transceiver desirable and fully interoperable with 5V supplied transceivers on the same bus. It also offers high speed, slope control and low-power standby modes of operation.

In this example, we looked for XRA1201. Click on part number header or on the link at the bottom of the result. This brings you to the product page. For example:
Click on Parts & Purchasing, highlighted with the blue arrow above. The screen changes to:
Notice the status column and the “Show obsolete parts” link. A legend tells you the definition of the different statuses. Click on the “Show obsolete parts” link to see EOL or OBS part numbers along with the Active part numbers, the legend still present:
Another method to find out if a part is OBS or EOL is to click on SUPPORT at the top:
And then Product Change Notifications:
Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:
If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was. If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.
