The SP207E-SP213E are enhanced transceivers intended for use in RS-232 and V.28 serial communication. These devices feature very low power consumption and single-supply operation making them ideal for space-constrained applications. Exar on-board charge pump circuitry generates fully compliant RS-232 voltage levels using small and inexpensive 0.1ìF charge pump capacitors. External +12V and -12V supplies are not required. The SP211E and SP213E feature a low-power shutdown mode, which reduces power supply drain to 1ìA. SP213E includes two receivers that remain active during shutdown to monitor for signal activity.
The SP207E-SP213E devices are pin-to-pin compatible with our previous SP207, SP208, SP21111 and SP213 as well as industry-standard competitor devices. Driver output and receiver input pins are protected against ESD to over ±15kV for both Human Body Model and IEC61000-4-2 Air Discharge test methods. Data rates of 120kbps are guaranteed, making them compatible with high speed modems and PC remote-access applications. Receivers also incorporate hysteresis for clean reception of slow moving signals.

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. 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.
