Description
AI
The SN75ALS172A comprises four line drivers with 3-state differential outputs. Which are designed to meet the requirements of ANSI Standards EIA/TIA-422-B and RS-485 and ITU Recommendation V.11. The device is optimized for balanced multipoint bus transmission at rates of up to 20Mbaud. Each driver features wide positive and negative common-mode output voltage ranges, making the driver suitable for party-line applications in noisy environments.
The SN75ALS172A 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 SN75ALS172A is characterized for operation from 0°C to 70°C.
