SP514 MultiMode Serial Transceiver
Copyright 2004 Sipex Corporation
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.
DESCRIPTION

ABSOLUTE MAXIMUM RATINGS

STORAGE CONSIDERATIONS
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.

For V.35 Termination, needs to be connected
for proper V.35 operation. A low on-
