Receiver hysteresis of 300 mV provides noise rejection on longer cable runs. Any remaining stock in the distribution channel is finite, and no last-time-buy window remains open. ## 250 kbps data rate — real-world fit At 250 kbps the MAX3232CDB handles the classic RS-232 sweet spot: 115.2 kbps and 230.4 kbps with margin, plus legacy 9600 baud. It will not stretch to 460.8 kbps or 1 Mbps — if your application needs those rates, this part is not the fit. The full-duplex capability means simultaneous transmit and receive on separate pairs, which matters for modems and multi-drop polled protocols. ## Supply voltage and 3.3V compatibility The 3V to 5.5V supply range directly answers the common question: yes, the MAX3232CDB works on a 3.3V rail. At 3.3V the charge-pump still generates the ±5V RS-232 output swing required by the standard. On a 5V rail the swing increases, improving noise margin on longer cables. ## Package and footprint — 16-SSOP Housed in a 16-SSOP (0.209\", 5.30mm width) package, surface-mount only. The body width is the narrower SSOP variant, not the wider SOIC — verify your land pattern against the 5.30 mm dimension before committing a board spin.","metaTitle":"MAX3232CDB RS-232 Transceiver, 250 kbps, 16-SSOP","metaDescription":"MAX3232CDB RS-232 transceiver, 2/2 drivers/receivers, 250 kbps data rate, 3V to 5.5V supply, 16-SSOP package.","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":"0°C~70°C","Supplier Device Package":"16-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232CDB/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of MAX3232CDB?","answer":"The MAX3232CDB is rated for a 250 kbps data rate."},{"question":"Is MAX3232CDB compatible with 3.3V?","answer":"Yes.

For a pin-compatible drop-in, look at the active MAX3232 family in the same 16-SSOP package — the base product number is MAX3232, and variants differ by temperature grade and package suffix.
