The SP510E is a highly integrated physical layer solution that is configurable to support multiple serial standards. It incorporates eight drivers and eight receivers (8TX/8RX), configurable for either differential (V.11 or V.35) or single ended (V.28 and V.10) signaling.
SP510E enables a Serial Communications Controller to implement a variety of serial port types including V.24, V.25, V.36, EIA-530, EIA-530-A, X.21, RS-232. The device architecture is designed to support the data and clock signals used in HDLC or SDLC serial ports as either DTE or DCE.
Operating configuration is programmable in system using the mode-select pins. The V.11 and V.35 modes include internal bus termination that may be switched in or out using the TERM_OFF pin. The SP510E is ideal for space constrained applications. It requires only a single 5V supply for full operation. The VL pin determines the receiver output voltage (VOH, down to 1.65V), for interfacing with lower voltage CPUs and FPGAs. For single supply operation at 5V the VL pin will be connected to VCC.
Fully compliant V.28 and V.10 driver output voltages are generated using the onboard charge pump. Special power sequencing is not required during system startup. Charge pump outputs are internally regulated to minimize power consumption. The SP510E requires only four 1µF capacitors for complete functionality. The device may be put into a low power shutdown mode when not in active use.
All receivers have fail-safe protection to put outputs into an output-high state when inputs are open, shorted, or terminated but idle.

Frequently Asked Questions
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.
