This means the manufacturer has announced end-of-life and is accepting final orders on a limited-time basis. For procurement, this is the trigger to secure lifetime buy quantities or qualify a drop-in replacement before the part becomes unavailable through authorized channels. Sourcing through independent distribution is the practical path for bridging production gaps or filling a BOM line after the LTB window closes. ## RS-232 transceiver with industrial temperature range The 300 mV of receiver hysteresis provides noise rejection on the RS-232 lines, reducing false bit transitions in electrically noisy industrial settings.","metaTitle":"TI MAX3232IDG4 RS-232 Transceiver, 250 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX3232IDG4: Full-duplex RS-232 transceiver, 2/2 drivers/receivers, 3V-5.5V supply, 250 kbps data rate, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","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-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Last Time Buy","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-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8656","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232IDG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or alternative for MAX3232IDG4?","answer":"Pin-compatible alternatives within the MAX3232 family include the MAX3232IDR (same SOIC package, different tape/reel quantity) or the MAX3232IPWR in TSSOP-16.
