DESCRIPTION
The SP26LV431 is a quad differential line driver that meets the specifications of the EIA
standard RS-422 serial protocol. The SP26LV431 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 SP26LV431 features a
driver enable control common to all four drivers that places the output pins in a high impedance
state. Since the cabling can be as long as 4,000 feet, the RS-422 drivers of the SP26LV431
are equipped with a wide common-mode output voltage range to accommodate ground
potential differences.
