At 250 kbps, this transceiver handles typical RS-232 asynchronous data up to about 31 KB/s. That is adequate for terminal interfaces, configuration ports, and low-throughput sensor links, but it will bottleneck a high-speed modem or a firmware-over-UART update running at 1 Mbps. The receiver hysteresis of 300 mV provides noise immunity on longer cable runs, reducing bit errors in electrically noisy environments. The MAX3232IDB is officially obsolete per the manufacturer's product status. Housed in a 16-SSOP (0.209\", 5.30mm width) surface-mount package, the MAX3232IDB fits tight PCB layouts common in space-constrained designs.","metaTitle":"MAX3232IDB RS-232 Transceiver, 250kbps, 3V-5.5V, 16-SSOP","metaDescription":"MAX3232IDB is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 250kbps data rate, 3V to 5.5V supply.","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":"-40°C~85°C","Supplier Device Package":"16-SSOP","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232IDB/alternatives.json"},"ai":{"faq":[{"question":"Can I use MAX3232IDB with a 3.3V supply?","answer":"Yes, the MAX3232IDB operates from 3V to 5.5V, so a 3.3V rail is within spec.
