In practice this means the receiver output stays valid when large voltage spikes slam across the isolation barrier — the kind of event you get from a motor drive IGBT switching, a relay bank, or a nearby lightning strike on a long cable run. A part with lower CMTI (some peers spec 25 kV/µs) may glitch or lose data under the same transient. For factory-floor RS485 networks, this margin buys reliability without external transient suppression on the logic side. The 32-BGA (15x11.25 mm) module uses a BGA footprint with 1.27 mm ball pitch — standard for a 4-layer PCB with a ground plane under the module. The package carries the isolated power transformer internally, so the board layout only needs to route the supply and data lines to the BGA pads.","metaTitle":"LTM2881HY-5#PBF RS422/RS485 Isolated Transceiver, 20 Mbps","metaDescription":"LTM2881HY-5#PBF from Analog Devices is a µModule isolated RS422/RS485 transceiver with 20 Mbps data rate, 2500 Vrms isolation, and integrated isolated power.","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-BBGA Module","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"1/1","Supplier Device Package":"32-BGA (15x11.25)","Common Mode Transient Immunity (Min)":"30kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$27.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$27.47000","currency":"USD"},{"qty":10,"price":"$25.33100","currency":"USD"},{"qty":25,"price":"$24.19240","currency":"USD"},{"qty":119,"price":"$21.63101","currency":"USD"},{"qty":238,"price":"$20.63479","currency":"USD"},{"qty":476,"price":"$19.63863","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2881fj.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of LTM2881HY-5#PBF?","answer":"The data rate is 20 Mbps, making it suitable for high-speed RS422 and RS485 networks such as Profibus or similar industrial fieldbuses."},{"question":"What are the alternatives to LTM2881HY-5#PBF?","answer":"A close functional peer is the ADM2582EBRWZ-REEL7 from Analog Devices, also an isolated RS485 transceiver with integrated DC/DC, but it offers a 16 Mbps data rate and 25 kV/µs CMTI versus the LTM2881's 20 Mbps and 30 kV/µs.
