DS96172/DS96174
RS-485/RS-422 Quad Differential Line Drivers
General Description
The DS96172 and DS96174 are high speed quad differential
line drivers designed to meet EIA Standard RS-485. The
devices have TRI-STATE
balanced multipoint data bus transmission at rates up to
10 Mbps. The drivers have wide positive and negative com-
mon mode range for multipoint applications in noisy environ-
ments. Positive and negative current-limiting is provided
which protects the drivers from line fault conditions over a
+12V to −7.0V common mode range. A thermal shutdown
feature is also provided and occurs at junction temperature
of approximately 160˚C. The DS96172 features an active
high and active low Enable, common to all four drivers. The
DS96174 features separate active high Enables for each
driver pair. Compatible RS-485 receivers, transceivers, and
repeaters are also offered to provide optimum bus perfor-
mance. The respective device types are DS96173,
DS96175, DS96176 AND DS96177.
