3 Description
The SN75ALS174A is a quadruple line driver with tri-
state differential outputs. It is designed to meet the
requirements of ANSI Standards EIA/TIA-422-B and
RS-485. This device is optimized for balanced
multipoint bus transmission at rates of up to 20
Mbit/s.
Spacer
Each driver features wide positive and negative
common-mode output voltage ranges that make them
suitable for party-line applications in noisy
environments.
The SN75ALS174A provides 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 SN75ALS174A is characterized for operation
from 0°C to 70°C.
