The SP514 is a single chip devices that supports eight (8) physical serial interface standards for Wide Area Network connectivity. The product is fabricated using a low power BiCMOS process technology, and incorporates a Sipex patented (5,306,954) charge pump allowing +5V only operation. The SP514 is 100% compatible with the SP504 multi-protocol serial transceiver IC. All applications using the SP504 can also use the SP514. The SP514 has slightly improved AC performance for its V.35 and V.11 drivers and receivers.
