The 250 kbps data rate covers standard serial ports, console cables, and point-of-sale terminals — anything that talks legacy RS-232 at moderate speed. If the board sees an engine bay, rooftop enclosure, or freezer, the industrial-temperature sibling (MAX3232IDBR) is the one to spec. At 5V it still works, so a legacy 5V-only design can drop this in without a re-spin. The charge-pump capacitors (four external 0.1 µF) are the same value across the whole supply range — no tweaking needed when you shift between 3.3V and 5V. ## 250 kbps data rate — is it enough? 250 kbps is the ceiling for this part. That covers standard serial ports with margin, plus common baud rates used in industrial serial protocols. The 16-SSOP body is 5.30 mm wide — narrower than the SOIC-16 footprint, so the PCB land pattern needs to match the SSOP pitch. Surface-mount only; no through-hole option exists for this order code. ## Compliance and lifecycle posture This part is a standard catalog line from Texas Instruments, still in regular production. The MAX3232 function is widely second-sourced across multiple vendors.","metaTitle":"MAX3232CDBR RS-232 Transceiver, 250 kbps, 16-SSOP","metaDescription":"Texas Instruments MAX3232CDBR full-duplex RS-232 transceiver, 2/2 driver/receiver, 3V to 5.5V supply, 250 kbps data rate, 0°C to 70°C, 16-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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-SSOP (0.209\\\", 5.30mm 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-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1500","priceTiers":[{"qty":1,"price":"$2.15000","currency":"USD"},{"qty":10,"price":"$1.92700","currency":"USD"},{"qty":25,"price":"$1.81800","currency":"USD"},{"qty":100,"price":"$1.54890","currency":"USD"},{"qty":250,"price":"$1.45432","currency":"USD"},{"qty":500,"price":"$1.27252","currency":"USD"},{"qty":1000,"price":"$1.05438","currency":"USD"},{"qty":2000,"price":"$1.02900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232CDBR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MAX3232CDBR and MAX3232CDR?","answer":"The difference is the package.
