New designs should not use this part. For existing BOM lines, the only sourcing channel is the independent distribution market — surplus inventory, new-old-stock, or broker-sourced material. No stock or lead-time number can be stated here because each procurement lot is sourced individually.","metaTitle":"MAX232ECDWRG4 RS-232 Transceiver, 250 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX232ECDWRG4 RS-232 transceiver, 2/2 drivers/receivers, 250 kbps data rate, 4.5V-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":"Tape & Reel (TR) Cut Tape (CT)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"MAX232","Receiver Hysteresis":"500 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c5745de4b7b700809b3bbb20b0189163.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX232ECDWRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MAX232ECDWRG4?","answer":"Pin-compatible replacements include the MAX232E (industrial temperature range) and the standard MAX232 (commercial temperature).
