Product details

Device identity and bus fit

The LTC2851IMS8#TRPBF is a full-duplex RS422/RS485 transceiver from Analog Devices, packing one driver and one receiver into an 8-MSOP package. 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.

Frequently asked questions

How does LTC2851IMS8#TRPBF compare to ADM3077EYRZ-REEL7?

Both are full-duplex RS422/RS485 transceivers in similar packages. 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.
