Clocked on the positive edge, it delivers complementary outputs at a rated clock frequency of 100 MHz, making it suitable for high-speed counter, register, and state-machine designs in avionics, satellite, and downhole instrumentation where the -55°C to 125°C operating range is required. ## Timing budget — 10.3 ns propagation delay at 5 V Max propagation delay of 10.3 ns at 5 V with a 50 pF load sets the timing closure window for back-to-back flip-flop stages or cascaded counters. Input capacitance is 10 pF, typical for 74AC inputs, so fan-out calculations should account for that load per driven gate. ## Package and mounting — 16-pin DIP, through hole Housed in a 16-pin DIP (0.300\", 7.62 mm body, PDIP-16), the CD74AC109E is a through-hole part for prototyping, legacy board repairs, or designs where socketed ICs are preferred for field service. The supplier device package is 16-PDIP. ## Lifecycle and compliance — active, RoHS3 Marked as active in the lifecycle stage with no NRND or EOL flags, this part remains in standard production. ROHS3 compliant, no exemption issues for EU or California markets.","metaTitle":"CD74AC109E 74AC Dual JK Flip-Flop, 100 MHz, 16-DIP","metaDescription":"TI CD74AC109E dual JK flip-flop with positive-edge trigger, 100 MHz clock, complementary outputs, 1.5V-5.5V supply, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":"74AC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"JK Type","Series":"74AC","Package":"Tube","Function":"Set(Preset) and Reset","Output Type":"Complementary","Trigger Type":"Positive Edge","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.5V ~ 5.5V","Input Capacitance":"10 pF","Number of Elements":"2","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"16-PDIP","Current - Quiescent (Iq)":"4 µA","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"1","Max Propagation Delay @ V, Max CL":"10.3ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.85","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.85000","currency":"USD"},{"qty":10,"price":"$0.74500","currency":"USD"},{"qty":25,"price":"$0.70000","currency":"USD"},{"qty":100,"price":"$0.57120","currency":"USD"},{"qty":250,"price":"$0.53060","currency":"USD"},{"qty":500,"price":"$0.45156","currency":"USD"},{"qty":1000,"price":"$0.36125","currency":"USD"},{"qty":2500,"price":"$0.32738","currency":"USD"},{"qty":5000,"price":"$0.31950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8671bbcf342a79d519b188ea62cd4508.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD74AC109E RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74AC109E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74AC109E when reusing this data.
