It belongs to the IsoPower and iCoupler series, using magnetic coupling technology for the isolation barrier. The part provides 2500Vrms of galvanic isolation and includes an on-chip isolated DC/DC converter, so you do not need a separate isolated power module on the board — that saves board area and simplifies the BOM for industrial RS232 ports that need to break ground loops. ## 460Kbps data rate and 25kV/µs CMTI — what they mean on a factory floor The 460Kbps data rate covers standard RS232 communication for PLCs, industrial terminals, and medical equipment serial links. The 25kV/µs minimum common-mode transient immunity means this part can sit on a board next to a motor drive or inverter switching at high dV/dt without losing data across the isolation barrier — a common failure point with optocoupler-based isolators that have slower transient rejection. The four channels are arranged as two inputs and two outputs on each side of the isolation barrier (2/2 configuration), all unidirectional. Rise and fall times are a tight 2.5ns typical, which keeps the signal edges clean even at the full 460Kbps rate. The supply range spans 3V to 5.5V on both sides of the isolation barrier, so it works with common 3.3V or 5V logic rails without needing a separate level shifter.","metaTitle":"ADM3252EABCZ RS232 Isolated Transceiver, 2500Vrms, 460Kbps","metaDescription":"ADI ADM3252EABCZ RS232 transceiver with integrated IsoPower isolated DC/DC, 2500Vrms isolation, 460Kbps data rate, 44-CSPBGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"IsoPower®, iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"RS232","Series":"IsoPower®, iCoupler®","Package":"Tray","Data Rate":"460Kbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"44-LBGA, CSPBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 85°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"44-CSPBGA (12x12)","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$23.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$23.08000","currency":"USD"},{"qty":10,"price":"$21.28600","currency":"USD"},{"qty":25,"price":"$20.32920","currency":"USD"},{"qty":80,"price":"$18.17675","currency":"USD"},{"qty":230,"price":"$17.33970","currency":"USD"},{"qty":440,"price":"$16.50259","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADM3252E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADM3252EABCZ be used with a 3.3V supply and single-ended RS232?","answer":"Yes. The supply voltage range is 3V to 5.5V on both sides of the isolation barrier, so a 3.3V rail works directly. The part is an RS232 transceiver, meaning it handles single-ended RS232 signals on the line side and presents logic-level signals on the controller side."},{"question":"What are the equivalent or alternative parts to ADM3252EABCZ?","answer":"The ADM3252EABCZ is a fairly unique part because it integrates both the signal isolation and the isolated power supply in a single RS232 transceiver. Within the same IsoPower family, the ADM3251E is a single-channel variant. For applications that do not need integrated isolated power, a separate isolated RS232 transceiver plus an isolated DC/DC module would be the fallback approach, but that increases board area and BOM count."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADM3252EABCZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADM3252EABCZ when reusing this data.
