DESCRIPTION
The SP507 is a monolithic IC that supports seven (7) popular serial interface standards for
DTE/DCE connectivity. The seven (7) drivers and seven (7) receivers transmit and receive
signals at over 20Mbps. The SP507 requires no additional external components for compliant
operation for all seven (7) modes of operation. All necessary termination is integrated within
the SP507 and is switchable when V.35 drivers, V.35 receivers, and V.11 receivers are used.
The SP507 can operate as either a DTE or DCE.
Additional features include 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 3-bit word into
the address decoder. Four (4) drivers and four (4) receivers in the SP507 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
rating conditions for extended periods of time may
affect reliability.

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. Exar ships the 80-
pin LQFP in Dry Vapor Barrier Bags with a humidity
indicator card and desiccant pack. The humidity indicator
should be below 30%RH.
