It belongs to the 74ACT family — advanced CMOS logic that runs on a 4.5V to 5.5V supply and delivers 24 mA source/sink per output. The inverted outputs simplify bus polarity matching in data latches, address registers, and status capture on a microprocessor bus. With a 100 MHz clock ceiling and 11.5 ns propagation delay at 5V, 50 pF, it keeps timing margins tight in synchronous designs. The -40°C to 85°C industrial temperature range suits it for factory automation, outdoor telecom, and motor-drive control boards — not just office-temperature gear. ## 100 MHz clock and 11.5 ns propagation delay — what they mean for the bus The 100 MHz clock rating sets the maximum toggle rate for the flip-flop itself. The 11.5 ns propagation delay from clock to output at 5V, 50 pF load determines the available setup time for the next device on the bus.","metaTitle":"SN74ACT534N D-Type Flip-Flop, 8-Bit, Tri-State Inverted","metaDescription":"SN74ACT534N 8-bit D-type flip-flop with tri-state inverted outputs, 100 MHz clock, 11.5 ns prop delay, industrial temp -40°C to 85°C.","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":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","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-PDIP","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":"$1.32","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.32000","currency":"USD"},{"qty":10,"price":"$1.17600","currency":"USD"},{"qty":25,"price":"$1.11600","currency":"USD"},{"qty":100,"price":"$0.91670","currency":"USD"},{"qty":250,"price":"$0.85692","currency":"USD"},{"qty":500,"price":"$0.75726","currency":"USD"},{"qty":1000,"price":"$0.59784","currency":"USD"},{"qty":2500,"price":"$0.56400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/62065fef7fd811cce416ec85c3520a8a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the exact electrical specifications of SN74ACT534N?","answer":"It operates on 4.5V to 5.5V supply, clocks at 100 MHz, and has a propagation delay of 11.5 ns at 5V, 50 pF.

The SN74ACT574N has non-inverted outputs. Both are 8-bit D-type flip-flops with tri-state outputs, same package, same speed grade. Choose the 534N when the downstream logic expects an active-low signal; choose the 574N for active-high."},{"question":"What is a suitable replacement or equivalent for SN74ACT534N?","answer":"The SN74ACT534N has no direct pin-compatible second source from another manufacturer. The closest functional peer in a different logic family is the SN74LS378N, but that is a 6-bit device with non-inverted outputs, slower (27 ns propagation delay), and limited to 0°C to 70°C. The 74F374SCX-NS is 8-bit with non-inverted outputs in a surface-mount package. Neither is a drop-in replacement. For a pin-compatible substitute, stay within the 74ACT family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ACT534N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ACT534N when reusing this data.
