It integrates five line drivers and three line receivers, a ratio that suits equipment with more transmit than receive channels — think industrial terminals, point-of-sale gear, or multi-port serial adapters where one UART talks to several peripherals. Operates from a 3V to 5.5V supply rail. Data rate is 250 kbps; receiver hysteresis is 600 mV. Temperature grade is commercial (0°C to 70°C), which covers most indoor and office-environment equipment. Not rated for industrial or automotive extended-temperature zones. ## Lifecycle and sourcing posture The MAX3238ECAI+ carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"MAX3238ECAI+ RS-232 Transceiver, 250 kbps, 5/3 Drivers","metaDescription":"MAX3238ECAI+ RS-232 transceiver, full duplex, 250 kbps data rate, 5 drivers/3 receivers, 3V-5.5V supply, 28-SSOP, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS232","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"28-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Receiver Hysteresis":"600 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"28-SSOP","Number of Drivers/Receivers":"5/3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.81000","currency":"USD"},{"qty":10,"price":"$10.85800","currency":"USD"},{"qty":25,"price":"$10.40760","currency":"USD"},{"qty":100,"price":"$9.16990","currency":"USD"},{"qty":250,"price":"$8.71984","currency":"USD"},{"qty":500,"price":"$8.15726","currency":"USD"},{"qty":1000,"price":"$7.48218","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9f1698298c157b20894badba6a92b8e3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX3238ECAI+ work with a 3.3V supply?","answer":"Yes. The supply voltage range is 3V to 5.5V, so it operates directly on a 3.3V rail. The internal charge pump generates the RS-232 output levels from that supply."},{"question":"What is the difference between MAX3238ECAI+ and MAX3232E?","answer":"The MAX3238ECAI+ provides 5 drivers and 3 receivers in a 28-SSOP package, versus the MAX3232E which has 2 drivers and 2 receivers in a smaller 16-pin package. The MAX3238 is the part to pick when your design needs more transmit channels than receive — common in multi-drop or terminal-server applications. Both operate from a 3V to 5.5V supply and run at 250 kbps."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3238ECAI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3238ECAI when reusing this data.
