If your application needs higher throughput, you would look at a different RS-232 family; the 250 kbps ceiling is the hard limit here.","metaTitle":"MAX3232IDRE4 RS-232 Transceiver, 250kbps, 16-SOIC","metaDescription":"Texas Instruments MAX3232IDRE4 RS-232 transceiver, full duplex, 2/2 drivers/receivers, 250kbps data rate, 3V-5.5V supply, 16-SOIC.","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)","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm 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-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd1772ada4594b24defcd65402aeacba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232IDRE4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MAX3232IDRE4?","answer":"For a pin-compatible replacement, look at the active MAX3232 family variants from Texas Instruments or other manufacturers — the 16-SOIC footprint and 2/2 driver/receiver configuration are common across the family.
