EIA-485/EIA-422 Quad Differential Drivers
General Description
Features
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.
Meets EIA-485 and EIA-422 standards

Monotonic differential output switching
TRI-STATE outputs
Designed for multipoint bus transmission
Common mode output voltage range: −7.0V to +12V
Operates from single +5.0V supply
Reduced power consumption

■
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.
Thermal shutdown protection
DS96F172 and DS96F174 are lead and function
compatible with the SN75172/174 or the AM26LS31/
MC3487

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: Above TA = 25°C, derate “E” package 13.3, “J” package 12.5, “W” package 7.1 mW/°C
Note 3: −55°C limit exceeds EIA standard RS−485 specification
Note 4: 0.2µF cap is connected between the output and Gnd to reduce oscillation.
Note 5: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are reference to ground unless otherwise specified.
Note 6: Δ|VOD| is the change in magnitude of VOD, that occurs when the input is changed between high and low levels.
Note 7: Δ|VOC| is the change in magnitude of the VOC that occurs when the input is changed between high and low levels.
