Overview of the SP505

The SP505 is a versatile and highly integrated serial transceiver, designed to enable software control over its interface modes. Building upon the capabilities of the SP504 , the SP505 supports the same hardware interface standards, including RS-232 (V.28), RS-422A (V.11), RS-449, RS-485, V.35, and EIA-530, while also adding support for V.36 and EIA-530A. Interface mode selection is facilitated through a 4-bit switch for configuring drivers and receivers. Manufactured using low-power BiCMOS process technology, the SP505 incorporates Exar’s patented charge pump technology (Patent No. 5,306,954), enabling operation with a single +5V power supply. The device is housed in an 80-pin JEDEC Quad FlatPack package, making it suitable for compact and efficient designs.
