It handles signaling at 20 Mbps — fast enough for high-throughput industrial backplanes or multi-drop sensor busses where the bus turnaround time limits the polling cycle. ## Receiver hysteresis and noise margin The 25 mV of receiver hysteresis filters out noise on long cable runs — on a 1 km RS485 bus with common-mode shifts, that hysteresis prevents the receiver from chattering on the differential signal's zero crossing. Supplied in an 8-MSOP (3.00 mm width) package — the same footprint as the 8-TSSOP, so it drops into existing layouts without a board spin. Supplied on tape-and-reel for volume assembly.","metaTitle":"LTC2851IMS8#TRPBF RS485 Transceiver, 20Mbps, 8-MSOP","metaDescription":"Analog Devices LTC2851IMS8#TRPBF RS422/RS485 full-duplex transceiver, 20 Mbps data rate, 3-3.6V supply, -40 to +85°C. 8-MSOP.

The LTC2851IMS8#TRPBF runs at 20 Mbps with 25 mV receiver hysteresis, while the ADM3077EYRZ-REEL7 runs at 16 Mbps with 100 mV hysteresis. The LTC2851 is the faster part; the ADM3077 offers higher noise immunity on the receiver side."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC2851IMS8TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC2851IMS8TRPBF when reusing this data.
