The tube packaging is the standard delivery form for prototype and low-volume builds; reel options may be available through distribution. ## Second-source consideration: ADM3067EBRZ The ADM3067EBRZ is a full-duplex RS485 transceiver from the same family, but it runs on a 3.0 V supply and pushes 50 Mbps — faster but at a lower voltage rail. The LTC2858HDD-1#PBF stays at 5 V, so swapping without adjusting the supply would overstress the 3 V part or under-drive the 5 V bus. The footprint is different too (10-DFN vs. 8-SOIC), so a board spin is required.","metaTitle":"LTC2858HDD-1#PBF RS422/RS485 Transceiver, 20Mbps","metaDescription":"Analog Devices LTC2858HDD-1#PBF RS422/RS485 transceiver, full duplex, 20Mbps, 4.5V-5.5V supply, -40°C to 125°C, 10-DFN.
