SP506 MultiMode Serial Transceiver
Copyright 2004 Sipex Corporation
The SP506 is a monolithic IC that supports eight (8) popular serial interface standards for DTE
to DCE connectivity. The SP506 is pin-to-pin compatible to our SP505 multi-protocol transceiver
but with faster throughput. The seven (7) drivers and seven (7) receivers can transmit and receive
signals at 20Mbps. As with the SP505, the SP506 requires no additional external components
for compliant operation for all of the eight (8) modes of operation. All necessary termination is
integrated within the SP506 and is switchable when V.35 drivers, V.35 receivers, and V.11
receivers are used. The SP506 can operate as either a DTE or DCE.
Additional features with the SP506 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 SP506 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
SP506 include separate enable pins for added convenience.

ABSOLUTE MAXIMUM RATINGS
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

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 40C 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 125C 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.
