The 160 MHz maximum clock frequency sets the upper bound for synchronous data capture — at that rate, the flip-flop can latch a new data word every 6.25 ns, suitable for high-speed register pipelines, address decoding, or state-machine storage in FPGA-less glue logic. The propagation delay of 4.5 ns at 5V with a 50 pF load gives the board designer a concrete timing budget: that 4.5 ns is the time from clock edge to valid Q output, which must fit within the setup-and-hold window of the downstream device. With a symmetric 32 mA output drive, this part can directly sink or source enough current to toggle an optocoupler LED or a small-signal relay coil, saving a discrete transistor per channel. The 1.65V to 5.5V supply range covers the three most common digital rails — 1.8V, 3.3V, and 5V — so the same part can serve in a low-power IoT node (1.8V) and a legacy industrial PLC (5V) without a voltage translator. The 10 µA quiescent current is low enough that the flip-flop's static draw is negligible in battery-powered designs; the dynamic power scales with the 4 pF input capacitance and the toggle rate. For BOM lines that need a dual-source hedge, the 74LVC1G79 base number is shared across several package variants — the DBVR suffix is the SOT-23-5 tape-and-reel option; the same die in a different package (e.g., DCKR in SC-70) is a drop-in functional equivalent if the footprint allows.","metaTitle":"SN74LVC1G79DBVR D-Type Flip-Flop, 160 MHz, SOT-23-5","metaDescription":"TI SN74LVC1G79DBVR single D-type flip-flop, positive-edge triggered, non-inverted output. 160 MHz clock, 1.65V–5.5V supply, –40°C to 125°C.","metaKeywords":null},"attributes":{"series":"74LVC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"D-Type","Series":"74LVC","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Standard","Output Type":"Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","Clock Frequency":"160 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 5.5V","Input Capacitance":"4 pF","Number of Elements":"1","Base Product Number":"74LVC1G79","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"10 µA","Current - Output High, Low":"32mA, 32mA","Number of Bits per Element":"1","Max Propagation Delay @ V, Max CL":"4.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":[{"qty":1,"price":"$0.46000","currency":"USD"},{"qty":10,"price":"$0.34900","currency":"USD"},{"qty":25,"price":"$0.31480","currency":"USD"},{"qty":100,"price":"$0.21750","currency":"USD"},{"qty":250,"price":"$0.18316","currency":"USD"},{"qty":500,"price":"$0.14882","currency":"USD"},{"qty":1000,"price":"$0.11448","currency":"USD"},{"qty":3000,"price":"$0.10303","currency":"USD"},{"qty":6000,"price":"$0.09731","currency":"USD"},{"qty":15000,"price":"$0.08872","currency":"USD"},{"qty":30000,"price":"$0.08300","currency":"USD"},{"qty":75000,"price":"$0.08100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa2a278407e821e7297ee4b32123a463.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G79DBVR/alternatives.json"},"ai":{"faq":[{"question":"What is the function of SN74LVC1G79DBVR?","answer":"It is a single D-type flip-flop that captures the logic level on the D input when the clock pin sees a rising edge (positive-edge triggered) and outputs that value on the Q pin without inversion. It is used for basic register storage, data synchronisation, and state-machine implementation in digital logic."},{"question":"Is SN74LVC1G79DBVR suitable for 3.3V operation?","answer":"Yes, the supply voltage range of 1.65V to 5.5V includes 3.3V. At 3.3V the propagation delay will be slightly longer than the 4.5 ns at 5V but still well within the timing margin for most 3.3V logic interfaces."},{"question":"How does SN74LVC1G79DBVR differ from SN74LVC1G79DCKR?","answer":"The two parts share the same base number 74LVC1G79 and identical electrical specifications. The difference is the package: DBVR is SOT-23-5, while DCKR is SC-70-5. The SOT-23-5 is slightly larger and easier to hand-solder; the SC-70 is more compact. Both are surface-mount and functionally interchangeable if the footprint is adjusted."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC1G79DBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC1G79DBVR when reusing this data.
