A 3V to 5.5V supply range lets it run from a common 3.3V rail or a legacy 5V bus without a separate regulator, simplifying BOM consolidation across mixed-voltage backplanes. ## Receiver hysteresis and noise margin for long cable runs The 150 mV of receiver hysteresis is the key differentiator here — it provides 50% more noise margin than the 100 mV typical of many RS485 parts, which matters when the cable runs past 100 meters in electrically noisy factory environments where common-mode transients couple into the twisted pair. Industrial temperature qualification from -40°C to 85°C means the part holds its timing and drive characteristics across the full range — no derating surprises when the enclosure sits in a sunlit panel or a cold warehouse. ## Package and integration fit Housed in an 8-SOIC (0.154-inch body width, 3.90 mm), the footprint is a standard SO-8 — no fine-pitch alignment needed, reworkable with a hot-air pencil, and the 1.27 mm pin pitch routes easily on a two-layer board. The tube packaging suits prototype and low-to-medium volume builds; for reel quantities the part is also orderable in tape-and-reel under a companion order code. ## Lifecycle and compliance status ROHS3 compliance covers the EU RoHS recast with all six substance restrictions plus the four phthalates — no exemption paperwork needed for EU-market equipment.","metaTitle":"LTC2863IS8-2#PBF RS485/RS422 Transceiver, 250 kbps","metaDescription":"Analog Devices LTC2863IS8-2#PBF RS485/RS422 full-duplex transceiver, 250 kbps data rate, 3V to 5.5V supply, 150 mV hysteresis, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Receiver Hysteresis":"150 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SO","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.27","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.27000","currency":"USD"},{"qty":10,"price":"$4.73500","currency":"USD"},{"qty":25,"price":"$4.47680","currency":"USD"},{"qty":100,"price":"$3.87990","currency":"USD"},{"qty":250,"price":"$3.68096","currency":"USD"},{"qty":500,"price":"$3.30290","currency":"USD"},{"qty":1000,"price":"$2.78558","currency":"USD"},{"qty":2500,"price":"$2.64630","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source to LTC2863IS8-2#PBF?","answer":"The ADM3070EARZ is the closest functional peer — same full-duplex RS422/RS485 protocol, same 250 kbps data rate, same 1/1 driver/receiver count, same 3.0V to 5.5V supply range, same industrial temperature grade, and same 8-SOIC package. The main difference is receiver hysteresis: 150 mV on the LTC2863 vs 100 mV on the ADM3070. The ADM3488ARZ is also a full-duplex 250 kbps part but with only 50 mV hysteresis.
