High Speed, +3.3V Quad RS-422
Differential Line Driver
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 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
SP431
are equipped
with a wide common-mode output voltage range to accommodate ground potential differ-
ences.
