EIA-485/EIA-422 Quad Differential Drivers

General Description

Features

n Meets EIA-485 and EIA-422 standards

n Monotonic differential output switching

n TRI-STATE outputs

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 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.

n Designed for multipoint bus transmission

n Common mode output voltage range: −7.0V to +12V

n Operates from single +5.0V supply

n Reduced power consumption

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

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.

n Thermal shutdown protection

n DS96F172 and DS96F174 are lead and function

compatible with the SN75172/174 or the

AM26LS31/MC3487

n Military temperature range available

n Qualified for MIL-STD-883C

n Standard military drawings available (SMD)

n Available in DIP (J), LCC (E), and Flatpak (W) packages
