It handles a 120 Kbps data rate on a 4.5 V to 5.5 V supply rail, with 650 mV of receiver hysteresis for noise immunity on longer cable runs. The through-hole DIP footprint suits legacy backplanes, industrial controller boards, and prototype assemblies where wave-solder or manual rework is the norm. ## Still active — no last-time-buy clock ticking ADI lists the ADM232LJNZ as Active with ROHS3 compliance. There is no NRND flag or EOL notice on this part, so it remains a safe line-item for both new builds and sustaining production. No date-code scramble or LTB deadline to manage. ## Package and mounting At 120 Kbps the part is tuned for RS232's original asynchronous character-oriented traffic — terminal links, PLC serial ports, and instrument data logs. It will not sustain the multi-Mbps rates of newer transceivers, but for its class the 650 mV of receiver hysteresis is a deliberate margin: it rejects ground-shift noise that creeps into long, unshielded serial cables in factory-floor or lab environments. ## Through-hole PDIP — board-fit and assembly note The 16-lead PDIP (0.300″ body width) is a standard 7.62 mm-pitch footprint shared by countless legacy RS232 parts. If your BOM calls for a surface-mount alternative, the ADM232LJRZ (SOIC-16 wide) is the same die in a reflow-compatible package. For new layouts the PDIP is fine for socketed or hand-assembled boards; for high-volume SMT lines the LJRZ variant avoids a separate wave-solder pass.","metaTitle":"ADM232LJNZ RS232 Transceiver, 120 Kbps, 2/2, 16-PDIP","metaDescription":"ADM232LJNZ RS232 transceiver, full duplex, 120 Kbps data rate, 2/2 driver/receiver, 4.5V-5.5V supply, 0-70°C, 16-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Receiver Hysteresis":"650 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-PDIP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.83","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.83000","currency":"USD"},{"qty":10,"price":"$4.33900","currency":"USD"},{"qty":25,"price":"$4.10240","currency":"USD"},{"qty":100,"price":"$3.55520","currency":"USD"},{"qty":250,"price":"$3.37292","currency":"USD"},{"qty":500,"price":"$3.02652","currency":"USD"},{"qty":1000,"price":"$2.58000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADM231L_232L_233L_234L_236L_237L_238L_239L_241L.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ADM232LJNZ?","answer":"The ADM232LJNZ supports a 120 Kbps data rate, which is sufficient for standard RS232 asynchronous serial links up to the original spec's distance limits."},{"question":"Can ADM232LJNZ replace MAX232?","answer":"The ADM232LJNZ is a functional equivalent to the industry-standard MAX232 — both are 2-driver/2-receiver full-duplex RS232 transceivers in a 16-pin DIP running on a 5 V supply.

The only difference is a 4.75 V minimum supply versus 4.5 V, which is negligible on a 5 V rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADM232LJNZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADM232LJNZ when reusing this data.
