DESCRIPTION
The DS96F172 and the DS96F174 are high speed
quad differential line drivers designed to meet EIA-
485 Standards. The DS96F172 and the DS96F174
offer improved performance 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 consumption.
The DS96F172 and the DS96F174 have TRI-STATE
outputs 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 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 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.
