SP26LV431 HIGH SPEED +3.3V QUAD RS-422 DIFFERENTIAL LINE DRIVER JUNE 2011 REV. 1.1.1 FEATURES GENERAL DESCRIPTION Quad Differential Line Drivers The SP26LV431 is a quad differential line driver that meets the specifications of the EIA standard RS-422 Compatible with the EIA standard for RS-422 serial serial protocol. The SP26LV431 features Exar s protocol BiCMOS process allowing low power operational High-Z Output Control characteristics of CMOS technology while meeting all of the demands of the RS-422 serial protocol over At Least 60Mbps Transmission Rates 60Mbps under load. The RS-422 protocol allows up 11ns Typical Driver Propagation Delays to 10 receivers to be connected to a multipoint bus transmission line. The SP26LV431 features a driver Less than 1ns Typical Output Skew enable control common to all four drivers that places Single +3.3V Supply Operation the output pins in a high impedance state. Since the cabling can be as long as 4,000 feet, the RS-422 Common Driver Enable Control drivers of the SP26LV431 are equipped with a wide Compatibility with the industry standard 26LV31 common-mode output voltage range to accommodate ground potential differences.
