It stores one byte of data on each rising clock edge and presents it on tri-state, non-inverted outputs — the standard register for address latching, data buffering, and pipeline stages in mixed-voltage digital systems. Outputs source and sink 24 mA — enough to drive a heavily loaded data bus or a bank of LEDs through a series resistor. ## Timing and drive for bus interface design Maximum propagation delay is 6.8 ns at 3.3 V with a 50 pF load — the spec that sets the data-valid window for the downstream latch. At 150 MHz the clock period is 6.67 ns, so the propagation delay consumes roughly one clock cycle; the designer must budget this into the hold-time margin on the receiving flip-flop. Input capacitance is 4 pF per pin, which matters when the register sits on a shared bus with multiple loads — each additional 74LVC574 adds 4 pF of capacitive load, reducing the bus's maximum toggle rate. Quiescent current is 10 µA typical, negligible in a powered system but relevant for battery-backed domains where the register holds state during sleep. ## Industrial temperature grade and package Housed in a 20-SOIC wide-body package (5.30 mm body width, 0.209-inch pitch), the NSR suffix indicates tape-and-reel or cut-tape delivery. The 20-SO footprint is a standard JEDEC outline; the PCB land pattern matches the common SOIC-20W pad geometry used across the 74LVC and 74AHCT families. ## Active lifecycle and compliance ROHS3 compliant per the manufacturer's declaration, with no exemptions for lead in solder or other restricted substances. No pin-compatible second-source is listed on the manufacturer's cross-reference, but the 74LVC574 function is a standard logic building block with multiple suppliers offering functionally equivalent parts in the same package.","metaTitle":"SN74LVC574ANSR 74LVC D-Type Flip-Flop, 150 MHz, 20-SOIC","metaDescription":"Texas Instruments SN74LVC574ANSR 74LVC D-Type flip-flop, 8-bit, 150 MHz clock, 1.65-3.6V supply, 24mA output drive, -40°C to 125°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":"74LVC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Type":"D-Type","Series":"74LVC","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Standard","Output Type":"Tri-State, Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.209\\\", 5.30mm Width)","Clock Frequency":"150 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 3.6V","Input Capacitance":"4 pF","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"20-SO","Current - Quiescent (Iq)":"10 µA","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"8","Max Propagation Delay @ V, Max CL":"6.8ns @ 3.3V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.89","priceTiers":[{"qty":1,"price":"$0.89000","currency":"USD"},{"qty":10,"price":"$0.79400","currency":"USD"},{"qty":25,"price":"$0.75400","currency":"USD"},{"qty":100,"price":"$0.61930","currency":"USD"},{"qty":250,"price":"$0.57888","currency":"USD"},{"qty":500,"price":"$0.51156","currency":"USD"},{"qty":1000,"price":"$0.40386","currency":"USD"},{"qty":2000,"price":"$0.38100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8a92bd19f5b84ad2c49a790fef49abd2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC574ANSR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVC574ANSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVC574ANSR when reusing this data.
