RS-485/RS-422 Quad Differential Line Drivers
General Description
The DS96172and DS96174are high speed quad differen-
tialline drivers designedto meetEIA Standard RS-485.The
devices have TRI-STATEÉ outputs andare optimizedfor
balanced multipoint data bus transmissionat ratesupto Mbps.The drivers have wide positiveand negative com-
mon mode rangefor multipointapplications innoisyenviron-
ments. Positive and negative current-limitingis provided
which protectsthe drivers fromline fault conditions overa
a12Vto b7.0V 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 perform-
ance.The respective device typesare 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: b7Vto a12V Operates from single a5V supply Thermal shutdown protection DS96172/DS96174are lead and function compatible
