SP505 Description
The SP505 is a highly integrated serial transceiver that allows software control of its interface modes. Similar to the SP504, the SP505 offers the same hardware interface modes for RS-232 (V.28), RS-422A (V.11), RS-449, RS-485, V.35, EIA-530 and includes V.36 and EIA-530A. The interface mode selection is done via a 4–bit switch for the drivers and receivers. The SP505 is fabricated using low–power BiCMOS process technology, and incorporates an Exar–patented (5,306,954) charge pump allowing +5V only operation. Each device is packaged in an 80–pin JEDEC Quad FlatPack package.

SP505 Theory of Operation
The SP505 is made up of five separate circuit blocks — the charge pump, drivers, receivers, decoder and switching array. Each of these circuit blocks is described in more detail below.
The SP505 charge pump is based on the SP504 design where Exar's patented charge pump design (5,306,954) uses a four-phase voltage shifting technique to attain symmetrical 10V power supplies.
