For new designs or BOM continuity, the closest functional replacement within the same family is the MAX3232EIDB (also in SSOP-16, same pinout and electrical specs). The 'E' suffix on the obsolete variant indicated lead-free (RoHS) finish; the replacement carries the same environmental compliance. At 250 kbps, this transceiver is suited for standard UART communication at common baud rates (115200, 57600, etc.) with margin. It is not a high-speed RS-232 part — designs requiring 1 Mbps or more need a different driver. The 300 mV hysteresis on the receiver inputs helps reject noise on longer cable runs, which is typical for industrial serial links.","metaTitle":"MAX3232EIDBE4 RS-232 Transceiver, 250 kbps, SSOP-16","metaDescription":"MAX3232EIDBE4 is a full-duplex RS-232 transceiver from TI. 3V to 5.5V supply, 250 kbps data rate, SSOP-16 package, -40°C to 85°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-SSOP (0.209\\\", 5.30mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"MAX3232","Receiver Hysteresis":"300 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dabd420645ea94ffbcfa5f91c9a9291d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232EIDBE4/alternatives.json"},"ai":{"faq":[{"question":"Is MAX3232EIDBE4 obsolete?","answer":"Yes, the MAX3232EIDBE4 is listed as obsolete.
