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.
