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.
