It handles the high-voltage level shifting internally — the supply range of 8V to 76V covers the typical VFD tube bias voltages, so you don't need a separate boost stage. The 2 mA supply current is the chip's own draw; the tube current comes from the supply rail, not the logic side. This is the part you reach for when you need to drive a multi-segment VF display from a microcontroller with minimal glue logic. ## Temperature grade and where it fits Rated for -40°C to 125°C, this is a full industrial-temperature part with headroom into automotive under-hood environments. That makes it a solid choice for outdoor signage, engine-bay displays, or any VFD application that sees temperature extremes. The wide supply range (8V to 76V) also means you can run it off an unregulated automotive battery line or a 48V telecom rail without a preregulator. ## Lifecycle and sourcing reality The MAX6934AQH+D is listed as Active and ROHS3 compliant. For BOM planning, you can treat it as a stable line item.","metaTitle":"MAX6934AQH+D VFD Tube Driver, 44-PLCC, -40°C to 125°C","metaDescription":"MAX6934AQH+D vacuum fluorescent display driver from Analog Devices. 4-wire serial interface, 8V to 76V supply, 2 mA supply current.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Interface":"4-Wire Serial","Display Type":"Vacuum Fluorescent (VF)","Mounting Type":"Surface Mount","Package / Case":"44-LCC (J-Lead)","lifecycle_stage":"eol_hot","Current - Supply":"2 mA","Voltage - Supply":"8V ~ 76V","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"44-PLCC (16.59x16.59)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.07","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.07000","currency":"USD"},{"qty":10,"price":"$10.17500","currency":"USD"},{"qty":25,"price":"$9.75360","currency":"USD"},{"qty":100,"price":"$8.59370","currency":"USD"},{"qty":250,"price":"$8.17192","currency":"USD"},{"qty":500,"price":"$7.64468","currency":"USD"},{"qty":1000,"price":"$7.01203","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/878a828a827540fd2dab9b9574982b9b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6934AQH+D RoHS compliant?","answer":"Yes, the MAX6934AQH+D is ROHS3 compliant."},{"question":"Is MAX6934AQH+D obsolete?","answer":"No, the MAX6934AQH+D is listed as Active with no end-of-life announcement."},{"question":"How do I program MAX6934AQH+D?","answer":"It uses a 4-wire serial interface — typically SPI-compatible — to shift in display data from a microcontroller.
