It integrates a magnetic coupling isolation barrier and an isolated DC-DC converter on the output side, so a single 3V to 3.6V supply on the logic side powers both the interface and the isolated bus-side circuitry. The part handles data rates up to 20Mbps and provides 2500Vrms of isolation, with a common-mode transient immunity of 30kV/µs minimum — enough to reject fast transients from motor drives or industrial inverters. The two unidirectional channels (one input on side 1, one output on side 2) are configured for half-duplex RS485 or full-duplex RS422 operation. At 20Mbps the LTM2881CV-3#PBF keeps the signal edges clean enough for short-haul RS422 links in test equipment, programmable logic controllers, or vision-system interfaces. The 2500Vrms isolation rating covers basic functional isolation for industrial environments where ground loops or voltage differences between equipment racks can exceed the transceiver's common-mode range. The 30kV/µs common-mode transient immunity means the receiver won't glitch when a contactor or VFD switches nearby — a spec that matters more than the headline isolation voltage for noisy-floor installations. ## Active production, no end-of-life risk It is ROHS3 compliant.","metaTitle":"LTM2881CV-3#PBF RS422/RS485 Isolated Transceiver, 20Mbps","metaDescription":"LTM2881CV-3#PBF µModule isolated RS422/RS485 transceiver, 20Mbps data rate, 2500Vrms isolation, 30kV/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":"3V ~ 3.6V","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":"$22.15","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$22.15000","currency":"USD"},{"qty":10,"price":"$20.35600","currency":"USD"},{"qty":25,"price":"$19.51200","currency":"USD"},{"qty":119,"price":"$17.19160","currency":"USD"},{"qty":238,"price":"$16.34786","currency":"USD"},{"qty":476,"price":"$15.29315","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2881fj.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LTM2881CV-3#PBF provide isolated power on the output side?","answer":"Yes, the LTM2881CV-3#PBF integrates an isolated DC-DC converter, so the bus-side circuitry is powered directly from the module without needing an external isolated supply."},{"question":"What are the alternatives for LTM2881CV-3#PBF?","answer":"A functional alternative is the ADM2582EBRWZ-REEL7 from Analog Devices, which also integrates isolated RS485/RS422 transceiver with isolated power.
