DS96172/DS96174 RS-485/RS-422 Quad Differential Line Drivers
June 1998
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 de-
vices have TRI-STATE
廬
outputs and are optimized for bal-
anced 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 鈭?.0V common mode range. A thermal shutdown
feature is also provided and occurs at junction temperature
of approximately 160藲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.
