That extra channel saves a second transceiver when the BOM calls for three RS232 ports. Supply voltage spans 5V to 15V, so the same part works on a 5V logic rail or a 12V industrial bus without a separate regulator. ## Supply flexibility and receiver noise margin Receiver hysteresis is specified at 400 mV, which filters out line noise on long RS232 cables without external schmitt triggers. Compared to the ADM202JNZ (2/2) or the ADM233LJNZ (2/2), the LT1039CN#PBF's 3/3 channel count and wider supply range are the deciding factors when the system needs three RS232 ports on a single DIP package. ## Active production and through-hole package The 18-pin DIP through-hole package is suitable for prototyping, legacy board repairs, or designs where socketed ICs are preferred for field service.","metaTitle":"LT1039CN#PBF RS232 Transceiver 3/3 Full Duplex 18-DIP","metaDescription":"LT1039CN#PBF RS232 transceiver, 3 drivers/3 receivers, full duplex, 5V-15V supply, 400 mV hysteresis, 0°C to 70°C, 18-DIP.

Electrically the part is identical to the non-#PBF version; the lead finish is the only difference. Confirm your board's solder profile accepts the ROHS-compliant finish before substituting."},{"question":"Can LT1039CN#PBF replace a MAX232?","answer":"The MAX232 is a 2/2 RS232 transceiver. The LT1039CN#PBF has three drivers and three receivers, so it is not a direct pin-for-pin replacement. If the design uses only two channels, the extra driver and receiver float, but the pinout differs — a board layout change is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1039CNPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1039CNPBF when reusing this data.
