SP505DS/08
SP505 MultiMode Serial Transceiver
Copyright 2000 Sipex Corporation
The SP505 is a monolithic device that supports eight (8) popular serial interface standards for DTE to
DCE connectivity. The SP505 is fabricated using a low power BiCMOS process technology, and
incorporates a Sipex patented (5,306,954) charge pump allowing +5V only operation. Seven (7) drivers
and seven (7) receivers can be configured via software for any of the above interface modes at any time.
The SP505 requires no additional external components for compliant operation for all of the eight (8)
modes of operation. All necessary termination is integrated within the SP505 and is switchable when
V.35 drivers, V.35 receivers, and V.11 receivers are used. The SP505 can operate as either a DTE or DCE.
Additional features with the SP505 include internal loopback that can be initiated in either single-ended
or differential modes. While in loopback mode, driver outputs are internally connected to receiver inputs
creating an internal signal path convenient for diagnostic testing. This eliminates the need for an external
loopback plug. The SP505 also includes a latch enable pin with the driver and receiver address decoder.
Tri-state ability for the driver and receiver outputs is controlled by supplying a 4-bit word into the address
decoder. Seven (7) drivers and one (1) receiver in the SP505 include separate enable pins for added
convenience. The SP505 is ideal for WAN serial ports in networking equipment such as routers,
switches, DSU/CSU's, and other access devices.

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.
