SP504 WAN Multi-Mode Serial Transceiver
■ +5V Only ■ Seven (7) Drivers and Seven (7) Receivers ■ Driver and Receiver Tri-State Control ■ Reduced V.35 Termination Network ■ Pin Compatible with the SP503 ■ Software Selectable Interface Modes: -RS-232E (V.28) -RS-422A (V.11, X.21) -RS-449 (V.11 & V.10) -RS-485 -V.35 -EIA-530 (V.11 & V.10) -EIA-530A (V.11 & V.10) -V.36 DESCRIPTION... 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.
