The outputs are tri-state and inverted — meaning when the output-enable is asserted, the bus sees the complement of the stored data; when de-asserted, the outputs go high-impedance and the bus floats. This is useful for shared data buses where multiple devices drive the same lines and you need bus isolation without external buffer gates. Runs on a 4.5V to 5.5V supply — this is a 5V logic family, not 3.3V. If your system rail is 3.3V, this part needs a level translator or a separate 5V supply. Clock frequency is 100 MHz, with a max propagation delay of 11.5 ns at 5V into a 50 pF load. That delay sets the timing budget for the data-to-output path — at 100 MHz the clock period is 10 ns, so the 11.5 ns delay means the output arrives after the next clock edge unless you pipeline or use a slower clock. For most 8-bit register applications below 50 MHz, the margin is comfortable. ## Industrial temperature range and 24 mA drive This covers factory-floor PLC cabinets, outdoor telecom shelters, and engine-bay-adjacent enclosures where the ambient stays below 85°C. Output drive is 24 mA source and sink — enough to drive a bus line, an LED indicator, or a downstream gate input without a separate buffer. The tri-state control lets you share the bus with other devices without contention. Input capacitance is 4.5 pF per input — light enough that the upstream driver sees a small load, which helps maintain signal integrity on a backplane or long PCB trace at 100 MHz. Quiescent current is 4 µA — negligible in a system that already draws milliamps for the rest of the logic. Not a low-power part by design, but the standby draw won't trouble a 5V rail. ## 20-TSSOP — fine-pitch surface-mount footprint The supplier device package is 20-TSSOP — same mechanical outline. This is a fine-pitch SMD; the 0.65 mm pitch requires a PCB with soldermask-defined pads and a stencil aperture that matches the land pattern. Surface-mount only — no through-hole variant exists for this order code. The tube packaging means it ships in anti-static tubes, not tape-and-reel, so pick-and-place lines need tube feeders or a transfer to tape.","metaTitle":"SN74ACT534PW D-Type Flip-Flop, 8-Bit, 100 MHz, 20-TSSOP","metaDescription":"Texas Instruments SN74ACT534PW D-Type flip-flop, 8-bit, tri-state inverted outputs, 100 MHz clock, 4.5-5.5V supply, -40 to 85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":"74ACT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"D-Type","Series":"74ACT","Package":"Tube","Function":"Standard","Output Type":"Tri-State, Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Input Capacitance":"4.5 pF","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-TSSOP","Current - Quiescent (Iq)":"4 µA","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"8","Max Propagation Delay @ V, Max CL":"11.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.26","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.26000","currency":"USD"},{"qty":10,"price":"$1.12900","currency":"USD"},{"qty":25,"price":"$1.07160","currency":"USD"},{"qty":100,"price":"$0.88010","currency":"USD"},{"qty":250,"price":"$0.82272","currency":"USD"},{"qty":500,"price":"$0.72706","currency":"USD"},{"qty":1000,"price":"$0.57399","currency":"USD"},{"qty":2500,"price":"$0.54150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/62065fef7fd811cce416ec85c3520a8a.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ACT534PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ACT534PW when reusing this data.
