It runs off a 5V nominal supply (4.75V to 5.25V) and includes 60 mV of receiver hysteresis to reject noise on long cable runs. The commercial temperature range (0°C to 70°C) suits indoor control panels, PLC interfaces, and building automation — not outdoor or under-hood environments. ## Package and mounting for the rework bench Housed in a 20-SOIC wide-body package (0.295\" body width, 7.50 mm), surface-mount only — no socket option, so plan for soldering with a fine-tip iron or hot-air station. The 20-SOIC wide footprint is common enough that a stencil and reflow profile for standard lead-free solder will work; no exposed pad to worry about.","metaTitle":"SN75ALS171ADW Texas Instruments RS422/RS485 Half-Duplex","metaDescription":"Texas Instruments SN75ALS171ADW half-duplex transceiver, 3/3 drivers/receivers, RS422/RS485, 4.75V-5.25V supply, 0°C-70°C, 20-SOIC.
