Do not plan on driving relays, long cables, or heavy bus loads directly; that is what a buffer or line driver is for. The quiescent current sits at just 8 µA, so this part is power-frugal in standby — useful for battery-backed or always-on sections of the board. The 10 pF input capacitance is typical for HC logic and will not load down a clock line noticeably. If you are daisy-chaining multiple registers on the same bus, keep an eye on total capacitive load — but for a single device, it is a non-issue. ## Lifecycle and sourcing — active, no LTB pressure The CD74HC574E is listed as Active and ROHS3 compliant. There is no last-time-buy notice, no NRND flag, no obsolescence risk on the horizon. For a BOM line, that means you can commit this part to production without worrying about a forced redesign in the next year.","metaTitle":"CD74HC574E 74HC D-Type Flip-Flop, 60 MHz, 20-DIP","metaDescription":"CD74HC574E 8-bit D-type flip-flop, 60 MHz clock, tri-state outputs, -55°C to 125°C, 20-DIP.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"D-Type","Series":"74HC","Package":"Tube","Function":"Standard","Output Type":"Tri-State, Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","Clock Frequency":"60 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 6V","Input Capacitance":"10 pF","Number of Elements":"1","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"20-PDIP","Current - Quiescent (Iq)":"8 µA","Current - Output High, Low":"7.8mA, 7.8mA","Number of Bits per Element":"8","Max Propagation Delay @ V, Max CL":"28ns @ 6V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.91","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.91000","currency":"USD"},{"qty":10,"price":"$0.81000","currency":"USD"},{"qty":25,"price":"$0.76880","currency":"USD"},{"qty":100,"price":"$0.63140","currency":"USD"},{"qty":250,"price":"$0.59028","currency":"USD"},{"qty":500,"price":"$0.52162","currency":"USD"},{"qty":1000,"price":"$0.41181","currency":"USD"},{"qty":2500,"price":"$0.38850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/94dbabd599dc004116938d2590c1e9dc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the propagation delay of CD74HC574E?","answer":"The maximum propagation delay is 28 ns at 6V supply with a 50 pF load. At lower supply voltages the delay will be slightly higher, but the 28 ns figure gives a solid timing budget for most 5V and 3.3V logic interfaces."},{"question":"How does CD74HC574E compare to SN74HC574N?","answer":"Both are 8-bit D-type flip-flops in the 74HC family with tri-state outputs and a 20-pin DIP package. The SN74HC574N is a functional equivalent from Texas Instruments — same logic function, same pinout, same 2V–6V supply range. The CD74HC574E carries a -55°C to 125°C temperature range, which is wider than the standard commercial/industrial range of most SN74HC574N variants. If your application does not need the extended temperature, either part works; for harsh environments, the CD74HC574E is the safer choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC574E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC574E when reusing this data.
