RS-485/RS-422 Quad Differential Line Drivers
General DescriptionThe DS96172 andDS96174are high speed quad differential
line drivers designedto meet EIAStandard RS-485.Thede-
vices have TRI-STATE® outputs andare optimizedforbal-
anced multipoint data bus transmissionat ratesupto Mbps.The drivers have wide positiveand negative com-
mon mode rangefor multipoint applicationsin noisy environ-
ments. Positive and negative current-limitingis provided
which protectsthe drivers fromline fault conditions overa
+12Vto −7.0V common mode range.A thermal shutdown
featureis also providedand occursat junction temperature approximately 160˚C. The DS96172 featuresan active
highand activelow Enable, commontoallfour drivers.The
DS96174 features separate active high Enablesfor each
driver pair. Compatible RS-485 receivers, transceivers,and
repeatersare also offeredto provide optimumbus perfor-
mance. The respective device types are DS96173,
DS96175, DS96176 AND DS96177.
Features MeetsEIA Standard RS-485and RS-422A Monotonic differential output switching Transmissionrateto10 Mbs TRI-STATE outputs Designedfor multipointbus transmission Common mode output voltage range:−7Vto +12V Operates from single +5V supply Thermal shutdown protection DS96172/DS96174are leadand function compatible
