DescriptionThe SP208EH/211EH/213EH devices are high speed enhanced multi-channel RS-232 line transceivers with improved electrical performance. The SP208EH/211EH/213EH series is a superior drop-in replacement to our previous versions as well as popular industry standards. All devices feature very low power CMOS construction and the Exar-patented (5,306,954) on-board charge pump circuitry that generates the +/-10V RS-232 voltage levels using 0.1μF charge pump capacitors. The SP211EH and SP213EH devices feature a low-power shutdown mode, which reduces power supply drain to 1μA. Enhancements to this series include a higher transmission rate of 500kbps, a lower power supply current at 3mA typical (no load), and superior ESD performance. The ESD tolerance has been improved for this series to over +/-15kV for both Human Body Model and IEC61000-4-2 Air Discharge test methods.

Frequently Asked Questions
For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps)
Maximum RS-232 Cable Length (ft)
In this example, we looked for XRA1201. When you hover over it, it will turn grey and you can click anywhere in the grey box. This brings you to the product page. For example:
Click on Parts & Purchasing, highlighted in yellow 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:
Another method to find out if a part is OBS or EOL is to click on SUPPORT:
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.
