The receiver inputs and driver outputs are specified across the full supply range, so the same device works in a 3.3V-only system or a mixed-voltage backplane. ## Temperature grade — indoor equipment only It is not specified for industrial or automotive use where the ambient might drop below freezing or exceed 70°C. For extended temperature, look at the industrial-grade MAX3232 variants in the same family. The 0.154-inch body width is the narrower SOIC variant, so verify the land pattern if your layout was originally designed for the wider 0.300-inch SO-16.","metaTitle":"MAX3232ECDR RS232 Transceiver, 250 kbps, 3V–5.5V, 16-SOIC","metaDescription":"MAX3232ECDR is a full-duplex RS232 transceiver with 2/2 driver/receiver count, 250 kbps data rate, 3V–5.5V supply range, and 300 mV receiver hysteresis.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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 (0.154\\\", 3.90mm Width)","Product Status":"Active","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-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dabd420645ea94ffbcfa5f91c9a9291d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232ECDR/alternatives.json"},"ai":{"faq":[{"question":"Is MAX3232ECDR compatible with 5V supply?","answer":"Yes, the MAX3232ECDR is rated for a 3V to 5.5V supply range, so it works directly on a 5V rail without any modification.
