SP504

® 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. The SP504 is suited for DTE–DCE applications. The SP504 requires only one external resistor per V.35 driver for compliant V.35 operation.
