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 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":["Logic ICs"],"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","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,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74ACT534N/alternatives.json"},"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.
