description
The
SN65ALS172A
and
SN75ALS172A
are
comprised of four line drivers with 3-state differential
outputs. They are designed to meet the requirements
of ANSI Standards EIA/TIA-422-B and RS-485 and
ITU Recommendation V.11. These devices are
optimized for balanced multipoint bus transmission at
rates of up to 20 Mbaud. Each driver features wide
positive and negative common-mode output voltage
ranges
making
them
suitable
for
party-line
applications in noisy environments.
The SN65ALS172A and SN75ALS172A provide
positive- and negative-current limiting and thermal
shutdown for protection from line fault conditions on
the transmission bus line. Shutdown occurs at a
junction temperature of approximately 150
°C.
The SN65ALS172A is characterized for operation
from – 40
°C to 85°C and the SN75ALS172A is
characterized for operation from 0
°C to 70°C.
