DESCRIPTION
The SP431 is a quad differential line driver that meets the specifications of the EIA standard
RS-422 serial protocol. The SP431 features Sipex's BiCMOS process allowing low power
operational characteristics of CMOS technology while meeting all of the demands of the
RS-422 serial protocol over 60Mbps under load. The RS-422 protocol allows up to 10
receivers to be connected to a multipoint bus transmission line. The SP431 features a driver
enable control common to all four drivers and a tri-state output. Since the cabling can be as
long as 4,000 feet, the RS-422 drivers of the SP431 are equipped with a wide common-mode
output voltage range to accomodate ground potential differences.
