DESCRIPTION
The SP516 is a monolithic device that supports eight (8) popular serial interface standards for
DTEtoDCEconnectivity. Theseven(7)driversandseven(7)receiverscantransmitandreceive
signals over 20Mbps. The SP516 requires no additional external components for compliant
operation for all of the eight (8) modes of operation. All necessary termination is integrated
within the SP516 and is switchable when V.35 drivers, V.35 receivers, and V.11 receivers
are used. The SP516 can operate as either a DTE or DCE.
Additional features with the SP516 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.
Thiseliminatestheneedforanexternalloopbackplug.TheSP516includesaterminationnetwork
disable pin for the V.35 and V.11 receiver input termination circuitry. High-Z 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 SP516 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
baggedandstoredbelow40°Cand60%RH.Iftheparts
are removed from the bag, they should be used within
48hoursorstoredinanenvironmentatorbelow20%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.
