There is no end-of-life notice or last-time-buy window. It remains a current-production part suitable for new designs and production builds. ## Package and rework — 8-SOIC, straightforward The 8-SOIC (0.154\" body width, 3.90 mm) is a standard surface-mount package. It reflows cleanly with a hot-air station or reflow oven.","metaTitle":"ADI ADM4855ARZ RS-485/RS-422 Full-Duplex Transceiver","metaDescription":"ADM4855ARZ is a 5 V full-duplex RS-485/RS-422 transceiver rated at 500 kbps, 1/1 driver/receiver, 20 mV hysteresis, -40°C to 85°C, 8-SOIC.
