They are designed to meet the requirements of ANSI Standards EIA/TIA-422-B and RS-485 and ITU Recommendation V.11. This device is 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 it suitable for party-line applications in noisy environments. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC 4A 4Y NC 4Z G 3Z NC 3Y 3A NC – No internal connection 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.
