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
transmission at rates up to 15 Mbps. The drivers have wide
positive and negative common mode range for multipoint ap-
plications 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 shutdown 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.
