If you have an existing BOM line that calls out this order code, you will need to source it from independent distribution or consider a pin-compatible replacement. The 16-TSSOP footprint and 2/2 driver/receiver count are common across the MAX3232 family, so a like-for-like swap is possible with a current-production sibling — verify the supply range and temperature grade against your design before committing the change. The 16-TSSOP body is 4.40 mm wide with a 0.65 mm pitch — a standard fine-pitch SOIC footprint that reflows cleanly with a typical lead-free profile. The TSSOP has low thermal mass; a 260°C peak reflow with a gentle ramp-down will lift the part without lifting the pad. No moisture sensitivity level is listed, but a 24-hour bake at 125°C before rework is cheap insurance if the original reel has been open.","metaTitle":"MAX3232CPWE4 RS-232 Transceiver, 250 kbps, 16-TSSOP","metaDescription":"MAX3232CPWE4 is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 250 kbps data rate, 3V–5.5V supply, 0°C–70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tube","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3232","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"16-TSSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232CPWE4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MAX3232CPWE4?","answer":"The MAX3232 family includes many 16-TSSOP variants with the same 2/2 driver/receiver count and wide supply range. A current-production sibling with matching footprint and temperature grade would be the natural cross-reference — check the supply voltage and operating temperature against your design before substituting."},{"question":"Can MAX3232CPWE4 work at 3.3V?","answer":"Yes. The supply range is 3V to 5.5V, so a 3.3V rail is well within the operating window. The RS-232 driver outputs will swing to the supply rail, and the receiver inputs tolerate up to ±25V, so it interfaces directly with a 3.3V UART without level shifting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3232CPWE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3232CPWE4 when reusing this data.
