Data rate hits 10 Mbps, well beyond the 115 kbps or 1 Mbps typical of older RS232 parts, so it handles high-speed serial links without bit errors. ## 2500Vrms isolation — what it buys you in the field The 2500Vrms rating is the reinforced isolation barrier between the RS232 bus side and the logic side. In a motor-drive cabinet or a PLC I/O card, that barrier protects the controller from ground loops, voltage surges, and common-mode transients that would otherwise fry the UART port. The common-mode transient immunity of 30 kV/µs (minimum) means the isolation holds even when a contactor slams in or a VFD switches at several kV/µs — the data link doesn't glitch or latch up. ## Integrated isolated power — one less module to source The isolated DC-DC converter built into the µModule generates the isolated-side supply rail internally. That saves a separate isolated power module (like a DCP01 or a discrete flyback) and the associated transformer, rectifier, and capacitor BOM. For a four-channel RS232 interface, it shrinks the board area to the 32-BGA footprint plus a few bypass caps. The trade-off: the BGA package (15x11.25 mm) requires a reflow profile and X-ray inspection — not a hand-solder repair job, but a standard SMT assembly line handles it fine. ## 10 Mbps data rate — faster than most RS232 needs At 10 Mbps, this part runs RS232 at speeds that overlap with RS422/RS485 territory. Most RS232 links run at 115.2 kbps or 1 Mbps; the extra margin means the transceiver can handle higher baud rates for firmware updates over a serial cable or for debug consoles that push data faster. The 60 ns typical rise/fall time and 100 ns max propagation delay keep the eye open at 10 Mbps over a few metres of cable. If your application only needs 115 kbps, the speed is still fine — the part doesn't force a minimum data rate. ## Active lifecycle — no LTB scramble ROHS3 compliance is confirmed, so it passes the EU material restriction requirements without an exemption. ## Closest functional alternative — ADM3252EABCZ The ADM3252EABCZ from Analog Devices is the nearest functional second-source: it is also an isolated RS232 transceiver with integrated power (IsoPower technology), four channels (2/2), and a 2500Vrms isolation rating. The key difference is data rate — the ADM3252EABCZ caps at 460 kbps, while the LTM2882HY-5#PBF runs at 10 Mbps. If your design doesn't need the higher speed or the extended temperature, the ADM3252EABCZ is a pin-compatible alternative for dual-sourcing. The ADM2682EBRIZ is an RS422/RS485 part, not a direct RS232 replacement.","metaTitle":"LTM2882HY-5#PBF Isolated RS232 Transceiver, 2500Vrms, 10Mbps","metaDescription":"LTM2882HY-5#PBF isolated RS232 transceiver with 2500Vrms isolation, 10Mbps data rate, integrated isolated power, -40°C to 105°C, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"µModule®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"RS232","Series":"µModule®","Package":"Tray","Data Rate":"10Mbps","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":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"60ns, 60ns","Supplier Device Package":"32-BGA (15x11.25)","Propagation Delay tpLH / tpHL (Max)":"100ns, 100ns","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://cdn.icboms.com/8b11213f2389fe59d4a25115bf64a57f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LTM2882HY-5#PBF include isolated power?","answer":"Yes, the µModule integrates an isolated DC-DC converter.
