It delivers 2500Vrms of galvanic isolation between the bus-side and logic-side interfaces, eliminating the need for a separate isolated power module on the BOM. ## What the 2500Vrms isolation and 30kV/µs CMTI mean for the bus The 2500Vrms isolation rating provides reinforced protection for RS422/RS485 nodes in industrial environments where ground potential differences between equipment cabinets can exceed tens of volts. The 30kV/µs minimum common-mode transient immunity keeps the receiver from latching or bit-flipping when a motor drive or relay bank switches a high-voltage bus — a common failure point in factory-floor RS485 networks. The integrated isolated power (Yes) means the LTM2881MPY-5#PBF generates its own isolated-side supply rail internally, so the BOM does not require a separate DC-DC converter or transformer driver for the bus side. ## Temperature range and deployment environment The 32-BGA (15x11.25mm) package is surface-mount only; the module's BGA footprint requires the standard PCB land pattern and a reflow profile compatible with a 32-ball array.","metaTitle":"LTM2881MPY-5#PBF ADI µModule RS422/RS485 Isolated","metaDescription":"LTM2881MPY-5#PBF isolated RS422/RS485 transceiver with 2500Vrms magnetic isolation, 20Mbps data rate, integrated isolated power, -55°C to 105°C.","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":"-55°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":"$44.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$44.96000","currency":"USD"},{"qty":10,"price":"$41.94800","currency":"USD"},{"qty":25,"price":"$40.19000","currency":"USD"},{"qty":119,"price":"$36.42210","currency":"USD"},{"qty":238,"price":"$35.16618","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2881fj.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LTM2881MPY-5#PBF provide isolated power or require an external DC-DC converter?","answer":"It includes an integrated isolated power supply, so no external DC-DC converter is needed for the bus-side rail.
