Frequently Asked Questions
What interface standards does the SN75ALS173NSE4 support?
The SN75ALS173NSE4 is compatible with RS-422-B, RS-423-B, RS-485, EIA V.10, V.11, CCITT X.26, and X.27 differential line standards. This broad compatibility makes it suitable for a wide range of industrial, telecommunications, and instrumentation serial communication applications over balanced twisted-pair cabling.
How many receiver channels does the SN75ALS173NSE4 have?
The SN75ALS173NSE4 integrates four independent differential line receiver channels in a 16-pin SOP package, each featuring Schmitt-trigger differential inputs for enhanced noise margin. All four channels share a common power supply but operate fully independently, ideal for multi-channel data acquisition designs.
What is the minimum output swing of the SN75ALS173NSE4?
The SN75ALS173NSE4 guarantees a minimum output swing of 2.25V, ensuring that the received differential signal translates cleanly to a TTL/CMOS-compatible logic level even in the presence of noise, cable losses, or termination loading at the end of long RS-422 or RS-485 transmission lines.
What package is the SN75ALS173NSE4 available in?
The SN75ALS173NSE4 is available in a 16-pin SOP (Small Outline Package), also designated as JESD-30 R-PDSO-G16, providing a compact SMT footprint suitable for high-density PCB layouts in industrial communication equipment and telecommunications line interface boards.
