The 25 mV receiver hysteresis filters out noise on long cable runs where common-mode shifts are the dominant signal-integrity risk. Analog Devices lists the MAX13444EASA+ as Active with ROHS3 compliance. ## 8-SOIC footprint and supply rails Supplied in tube; reel quantities available on request. Single 5 V supply (±5 %) simplifies power-tree design — no separate I/O or analog rails. The 250 kbps data rate is a bus-speed ceiling, not a toggle-rate floor; the part also operates correctly at lower baud rates down to DC.","metaTitle":"MAX13444EASA+ RS-485/RS-422 Transceiver, 250 kbps, 8-SOIC","metaDescription":"MAX13444EASA+ half-duplex RS-485/RS-422 transceiver from Analog Devices. 250 kbps data rate, 4.75-5.25 V supply, -40 to +125 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Type":"Transceiver","Duplex":"Half","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"25 mV","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.62000","currency":"USD"},{"qty":10,"price":"$6.88400","currency":"USD"},{"qty":25,"price":"$6.56360","currency":"USD"},{"qty":100,"price":"$5.69900","currency":"USD"},{"qty":250,"price":"$5.44288","currency":"USD"},{"qty":500,"price":"$4.96264","currency":"USD"},{"qty":1000,"price":"$4.32230","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate and protocol support for MAX13444EASA+?","answer":"It is a half-duplex transceiver supporting both RS-485 and RS-422 at 250 kbps."},{"question":"What package does MAX13444EASA+ come in?","answer":"The 8-SOIC surface-mount package (0.154-inch body width, 3.90 mm) with a tube delivery format.
