DESCRIPTION...
Rev: A Date:1/27/04
The SP504 is a single chip device that supports eight (8) physical serial interface standards
for Wide Area Network Connectivity. The SP504 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 SP504 is suited for DTE–DCE
applications. The SP504 requires only one external resistor per V.35 driver for compliant V.35
operation.

... Although many applications do not use all these signals, some applications may need to support extra functions such as diagnos- tics. The SP504 supports enough transceivers for the primary channels of data, clock and control signals.
