It handles data rates up to 120Kbps across a supply range of 3V to 5.5V, making it a straight drop-in for mixed-voltage serial ports on industrial controllers, point-of-sale terminals, and embedded PC peripherals. The 300 mV receiver hysteresis cleans up noisy RS-232 lines — edges that jitter within that band won't toggle the output, which saves the UART from false start-bit detections on long cable runs in factory-floor environments. ## 28-SOIC footprint and board-fit Surface-mount assembly with no exposed pad — standard reflow profile for JEDEC MSL-1 parts applies. The tube packaging means it feeds through most pick-and-place feeders without a reel change.","metaTitle":"MAX3243CWI+ RS-232 Transceiver, 3/5 Full Duplex, 120Kbps","metaDescription":"MAX3243CWI+ RS-232 transceiver from Analog Devices. 3 drivers, 5 receivers, full duplex, 120Kbps data rate, 3V-5.5V supply, 28-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Surface Mount","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Receiver Hysteresis":"300 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"28-SOIC","Number of Drivers/Receivers":"3/5"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.91","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.91000","currency":"USD"},{"qty":10,"price":"$9.85900","currency":"USD"},{"qty":25,"price":"$9.40000","currency":"USD"},{"qty":100,"price":"$8.16200","currency":"USD"},{"qty":250,"price":"$7.79520","currency":"USD"},{"qty":500,"price":"$7.10736","currency":"USD"},{"qty":1000,"price":"$6.19029","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9cba33f1020c15857558a6ab9c553fae.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3243CWI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3243CWI when reusing this data.
