DS96172/DS96174

RS-485/RS-422 Quad Differential Line Drivers

General Description

Features

n Meets EIA Standard RS-485 and RS-422A

n Monotonic differential output switching

n Transmission rate to 10 Mbs

n TRI-STATE outputs

The DS96172 and DS96174 are high speed quad differential

line drivers designed to meet EIA Standard RS-485. The de-

vices have TRI-STATE^®outputs and are optimized for bal-

anced multipoint data bus transmission at rates up to

10 Mbps. The drivers have wide positive and negative com-

mon mode range for multipoint applications in noisy environ-

ments. 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 and occurs at junction temperature

of approximately 160˚C. The DS96172 features an active

high and active low Enable, common to all four drivers. The

DS96174 features separate active high Enables for each

driver pair. Compatible RS-485 receivers, transceivers, and

repeaters are also offered to provide optimum bus perfor-

mance. The respective device types are DS96173,

DS96175, DS96176 AND DS96177.

n Designed for multipoint bus transmission

n Common mode output voltage range: −7V to +12V

n Operates from single +5V supply

n Thermal shutdown protection

n DS96172/DS96174 are lead and function compatible

with the SN75172/75174 or the AM26LS31/MC3487

respectively
