Input capacitance is 3 pF typical — light enough that a 115 MHz clock tree does not need a dedicated buffer for every branch, though the fan-out limit depends on the trace impedance and the driver's rise time. ## Temperature grade and package fit Supplied in tube format — the 20-TSSOP body is moisture-sensitive per J-STD-020; the floor life at 30°C/60% RH depends on the MSL level printed on the bag, which should be verified before the reel is opened for hand assembly or rework.","metaTitle":"SN74AHC574PW TI 74AHC D-Type Flip-Flop, 115 MHz, 20-TSSOP","metaDescription":"Texas Instruments SN74AHC574PW octal D-type flip-flop, 115 MHz clock, 10.6 ns prop delay at 5V, 2-5.5V supply, -40 to 85°C.

The LVC variant runs at 150 MHz and delivers 24 mA output drive versus 8 mA, but its supply range tops out at 3.6 V — it cannot operate at 5 V like the AHC part. For a 3.3 V board the LVC is a drop-in swap; for a 5 V bus the AHC stays the correct choice."},{"question":"Will SN74AHC574PW drop into a board laid out for SN74LVC574APWT?","answer":"Yes, both parts share the same 20-TSSOP footprint (0.65 mm pitch, 4.40 mm body width). The pinout is identical for the D-type octal flip-flop with tri-state outputs. The only board-level consideration is the supply rail: if the original design runs at 5 V, the AHC part works and the LVC does not; if at 3.3 V, either fits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHC574PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHC574PW when reusing this data.
