It uses a 4-wire serial interface to shift out display data to the VFD tube's grid and anode segments. The part accepts a supply range of 8V to 76V, covering both the logic rail and the high-voltage anode supply typical in automotive dashboard and industrial VFD panels. Supply current sits at 1.65 mA, which keeps the power budget tight in always-on displays. The operating temperature range of -40°C to 125°C qualifies it for under-hood or outdoor equipment where ambient heat cycles are severe. The 44-PLCC package (J-lead, surface mount) saves board area compared to through-hole alternatives. ## 8V to 76V supply — what it means for the BOM The wide supply range (8V to 76V) means this driver can run directly off an unregulated 12V or 24V automotive rail without a separate boost converter for the VFD anode. That saves a DC-DC stage and its associated inductor and capacitor cost. At the high end, 76V covers most VFD tube bias requirements without an external voltage multiplier. The 1.65 mA supply current is the chip's own draw; the actual VFD tube current comes from the anode supply through the driver's output stages, so the total system current depends on the tube's segment load. ## Lifecycle and sourcing reality The MAX6922AQH+D carries an Active lifecycle status from Maxim Integrated. No end-of-life notice or last-time-buy schedule is published. ROHS3 compliance is confirmed.","metaTitle":"MAX6922AQH+D VFD Tube Driver, 4-Wire Serial, 44-PLCC","metaDescription":"MAX6922AQH+D is an active VFD tube driver from Maxim Integrated. 4-wire serial interface, 8V-76V supply, 1.65 mA supply current. -40°C to 125°C.","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":"1.65 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":"$10.72","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.72000","currency":"USD"},{"qty":10,"price":"$9.68500","currency":"USD"},{"qty":25,"price":"$9.23440","currency":"USD"},{"qty":100,"price":"$8.01820","currency":"USD"},{"qty":250,"price":"$7.65784","currency":"USD"},{"qty":500,"price":"$6.98212","currency":"USD"},{"qty":1000,"price":"$6.08121","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/878a828a827540fd2dab9b9574982b9b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What voltage does the MAX6922AQH+D require?","answer":"The supply voltage range is 8V to 76V.
