Typical applications include factory automation, motor-drive interfaces, building management networks, and any RS422/RS485 bus that needs a clean, isolated boundary. ## Package and mounting The 20 Mbps data rate supports high-speed RS422 links and fast RS485 networks without sacrificing bus length. At that speed, the 30 kV/µs common-mode transient immunity becomes the real differentiator: it keeps the receiver from latching or missing bits when a motor drive or VFD kicks a kilovolt transient across the isolation barrier. The ADM2582EBRWZ-REEL7, a close functional peer, tops out at 16 Mbps and 25 kV/µs CMTI — so if you're pushing the bus speed or have a particularly noisy environment, the LTM2881 holds a measurable edge. ## Commercial temp range — design-in note If the board needs to live in an unheated cabinet or near a hot motor drive, the industrial-temperature ADM2582EBRWZ-REEL7 (-40°C to 85°C) is a better fit, though you'll trade a few Mbps and some CMTI margin. The LTM2881CV-5#PBF comes in a 32-BLGA package (15x11.25 mm) with surface-mount termination; the LGA footprint is straightforward for reflow but check your stencil aperture for the large thermal pad — it carries the heat away from the integrated DC/DC converter. It is ROHS3 compliant.","metaTitle":"LTM2881CV-5#PBF Isolated RS422/RS485 Transceiver, 20 Mbps","metaDescription":"LTM2881CV-5#PBF from Analog Devices is a µModule isolated RS422/RS485 transceiver with 20 Mbps data rate, 2500 Vrms isolation, and 30 kV/µs CMTI.","metaKeywords":null},"attributes":{"series":"µModule®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"RS422, RS485","Series":"µModule®","Package":"Tray","Data Rate":"20Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"32-BLGA","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"0°C ~ 70°C","Inputs - Side 1/Side 2":"1/1","Supplier Device Package":"32-LGA (15x11.25)","Common Mode Transient Immunity (Min)":"30kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.1","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$21.10000","currency":"USD"},{"qty":10,"price":"$19.39600","currency":"USD"},{"qty":25,"price":"$18.59160","currency":"USD"},{"qty":119,"price":"$16.38067","currency":"USD"},{"qty":238,"price":"$15.57672","currency":"USD"},{"qty":476,"price":"$14.57176","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2881fj.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will LTM2881CV-5#PBF drop into a panel that was specified around ADM2582EBRWZ-REEL7 without rewiring?","answer":"The ADM2582EBRWZ-REEL7 is a close functional peer but not a pin-for-pin drop-in.
