It delivers complementary outputs (Q and Q̅) and operates across a wide supply range of 1.65 V to 5.5 V, making it a direct fit for mixed-voltage automotive ECUs, body controllers, and ADAS sensor interface boards where a single-bit latch with asynchronous initialization is needed. The 140 MHz clock frequency supports high-speed data latching in CAN transceiver handshake or SPI bus isolation stages. ## AEC-Q100 qualification and temperature range This part carries AEC-Q100 qualification, the automotive industry's stress-test standard for integrated circuits. Combined with an operating temperature range of -40°C to 125°C, it is rated for under-hood and engine-bay environments where ambient heat and thermal cycling are routine. The 74LVC logic family also provides 5 V tolerant inputs, so it can interface directly with legacy 5 V sensors or microcontrollers without external level shifters. ## Output drive and propagation delay Each output can source or sink 24 mA, enough to drive a standard logic input or a low-power LED indicator directly. Maximum propagation delay is 5.4 ns at 5 V with a 50 pF load, which keeps setup-and-hold margins tight in a 140 MHz clocked system. Quiescent current is 10 µA, so the flip-flop adds negligible standby draw in battery-backed automotive modules. ## Sourcing and lifecycle The SN74LVC2G74QDCURQ1 is listed as Active in production status and is ROHS3 compliant.","metaTitle":"SN74LVC2G74QDCURQ1 D-Type Flip-Flop, AEC-Q100, 140 MHz","metaDescription":"TI SN74LVC2G74QDCURQ1 single D-type flip-flop with set/reset, AEC-Q100 qualified, 1.65-5.5 V supply, 140 MHz clock, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, 74LVC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"D-Type","Series":"Automotive, AEC-Q100, 74LVC","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Set(Preset) and Reset","Output Type":"Complementary","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"8-VFSOP (0.091\\\", 2.30mm Width)","Clock Frequency":"140 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 5.5V","Input Capacitance":"5 pF","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"8-VSSOP","Current - Quiescent (Iq)":"10 µA","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"1","Max Propagation Delay @ V, Max CL":"5.4ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.83","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.83000","currency":"USD"},{"qty":10,"price":"$0.73500","currency":"USD"},{"qty":25,"price":"$0.69000","currency":"USD"},{"qty":100,"price":"$0.56320","currency":"USD"},{"qty":250,"price":"$0.52312","currency":"USD"},{"qty":500,"price":"$0.44520","currency":"USD"},{"qty":1000,"price":"$0.35616","currency":"USD"},{"qty":3000,"price":"$0.32277","currency":"USD"},{"qty":6000,"price":"$0.31500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aac65d27e22c24d7babe07f1cfa8dcc9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74LVC2G74QDCURQ1 AEC-Q100 qualified?","answer":"Yes, the SN74LVC2G74QDCURQ1 is part of the Automotive, AEC-Q100 series, meaning it has passed the automotive stress qualification tests for reliability in harsh environments."},{"question":"Can SN74LVC2G74QDCURQ1 replace SN74LVC2G74DCUR?","answer":"Yes, the SN74LVC2G74QDCURQ1 is pin-compatible and functionally identical to the SN74LVC2G74DCUR.
