® SP514 WAN Multi-Mode Serial Transceiver ■ +5V Only ■ Seven (7) Drivers and Seven (7) Receivers ■ Driver and Receiver Tri-State Control ■ Reduced V.35 Termination Network ■ Pin Compatible with the SP504 ■ Improved Propagation Delays ■ Software Selectable Interface Modes: -RS-232E (V.28) -RS-422A (V.11, X.21) -RS-449 (V.11 & V.10) -RS-485 -V.35 -EIA-530 (V.11 & V.10) -EIA-530A (V.11 & V.10) -V.36 DESCRIPTION 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. V.35 EIA-530 WAN Rev. 3/05/04 SP514 Multi–Mode Serial Transceiver 1 © Copyright 2004 Sipex Corporation ABSOLUTE MAXIMUM RATINGS STORAGE CONSIDERATIONS These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. Due to the relatively large package size of the 80-pin quad flat-pack, storage in a low humidity environment is preferred. Large high density plastic packages are moisture sensitive and should be stored in Dry Vapor Barrier Bags. Prior to usage, the parts should remain bagged and stored below 40°C and 60%RH. If the parts are removed from the bag, they should be used within 48 hours or stored in an environment at or below 20%RH. If the above conditions cannot be followed, the parts should be baked for four hours at 125°C in order remove moisture prior to soldering. Sipex ships the 80-pin QFP in Dry Vapor Barrier Bags with a humidity indicator card and desiccant pack.The humidity indicator should be below 30%RH.
