EIA-485/EIA-422 Quad Differential Drivers
General Description
The DS96F172 and the DS96F174 are high speed quad dif-
ferential line drivers designed to meet EIA-485 Standards.
The DS96F172 and the DS96F174 offer improved perfor-
mance due to the use of L-FAST bipolar technology. The use
of LFAST technology allows the DS96F172 and DS96F174
to operate at higher speeds while minimizing power con-
sumption.
The DS96F172 and the DS96F174 have TRI-STATE^® out-
puts and are optimized for balanced multipoint data bus trans-
mission at rates up to 15 Mbps. The drivers have wide positive
and negative common mode range for multipoint applications
in noisy environments. 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 shut-
down feature is also provided. The DS96F172 features an
active high and active low Enable, common to all four drivers.
The DS96F174 features separate active high Enables for
each driver pair.
