The 300 mV of receiver hysteresis provides clean switching on noisy lines without external filtering. This part is packaged in a 16-SOIC (3.90 mm width) for surface-mount assembly. The wide supply range is the defining feature of the MAX3232 family. It allows the transceiver to run from a 3.3V rail (common in modern MCU-based designs) or a 5V rail (legacy industrial logic) without a separate level translator. The charge-pump circuitry generates the RS-232 bipolar voltages internally — ±5.5V typical — from the single supply. If the design requires extended temperature, look at the industrial-grade MAX3232 variants (e.g., MAX3232EIPWR) that cover -40°C to +85°C.","metaTitle":"MAX3232ECD RS-232 Transceiver, 250 kbps, 3V-5.5V, SOIC-16","metaDescription":"Texas Instruments MAX3232ECD RS-232 transceiver, 2/2 drivers/receivers, full duplex, 250 kbps, 3V to 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":"Tube","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":"0°C~70°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$34.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dabd420645ea94ffbcfa5f91c9a9291d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX3232ECD/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MAX3232ECD?","answer":"Texas Instruments has not published a direct replacement for the MAX3232ECD. However, the MAX3232EID (industrial temp, -40°C to 85°C) or MAX3232ECPW (same commercial temp, different package) are functionally similar and may be pin-compatible. Verify the package and temperature grade against your BOM before substituting."},{"question":"Does MAX3232ECD meet 3.3V operation?","answer":"Yes, the MAX3232ECD is specified for a supply voltage range of 3V to 5.5V, so it operates correctly on a 3.3V rail. The internal charge pump generates the RS-232 voltage levels from the 3.3V supply without external components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MAX3232ECD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MAX3232ECD when reusing this data.
