It handles the voltage-level translation between a 5V UART and the ±12V RS-232 bus, so you don't need a separate level shifter or charge-pump controller. ## Data rate and signal margin at the bus At 120 kbps, this transceiver is fast enough for legacy RS-232 links up to about 15 meters — think barcode scanners, serial printers, and industrial modems. The 500 mV receiver hysteresis cleans up noise on long cables, reducing bit errors without external filtering. If your application needs 1 Mbps or higher (e.g., high-speed instrumentation), the TRS202EIDW won't keep up; you'd step to a 3V-to-5.5V part like the MAX3232 family. For 120 kbps links, the hysteresis margin is a real advantage over cheaper transceivers that skip it. ## Package and board integration Housed in a 16-SOIC (0.295-inch body width, 7.50 mm), the TRS202EIDW uses a standard footprint that routes easily on two-layer boards. The 0.050-inch pitch doesn't demand fine-line etching, and the wide body gives good thermal contact to the copper pour for heat sinking. For automated pick-and-place, confirm the tube-to-tape conversion with your assembler. ## Lifecycle and sourcing posture It is RoHS3 compliant (lead-free), so it meets current EU and global environmental requirements without a waiver. No stock-holding claim; we source through authorized distribution and verified independent channels.","metaTitle":"TRS202EIDW RS-232 Transceiver 120 kbps 2/2 Full Duplex","metaDescription":"Texas Instruments TRS202EIDW RS-232 transceiver, 2/2 driver/receiver, 120 kbps, full duplex, 4.5V-5.5V supply, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS232","Data Rate":"120Kbps","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Receiver Hysteresis":"500 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.57","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.57000","currency":"USD"},{"qty":10,"price":"$1.40700","currency":"USD"},{"qty":25,"price":"$1.32760","currency":"USD"},{"qty":100,"price":"$1.13120","currency":"USD"},{"qty":250,"price":"$1.06212","currency":"USD"},{"qty":500,"price":"$0.92936","currency":"USD"},{"qty":1000,"price":"$0.77004","currency":"USD"},{"qty":2500,"price":"$0.75150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/89fd4ae178e29bac39654ae558973f97.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of TRS202EIDW?","answer":"The TRS202EIDW supports a data rate of 120 kbps, which is typical for standard RS-232 communication at cable lengths up to 15 meters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TRS202EIDW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TRS202EIDW when reusing this data.
