Each of the two elements is a single-bit, positive-edge-triggered JK flip-flop with complementary outputs and separate Set (Preset) and Reset inputs, giving the designer independent control over initialisation state. The 150 MHz maximum clock frequency sets the upper toggle rate — at this speed the 8 ns propagation delay at 5V, 50 pF load consumes roughly 1.2 clock periods in flight, so cascaded stages need a timing margin check at the system level. Supply voltage is 4.5V to 5.5V — this is a 5V-only bipolar part; it does not operate from 3.3V or lower rails without a level translator on the inputs and outputs. Quiescent current is 17 mA typical, and the output drive capability is 1 mA source / 20 mA sink — sufficient for driving one or two standard TTL loads but not high-fanout buses without buffering.","metaTitle":"Texas Instruments SN74F109N JK Flip-Flop, 150 MHz, 16-PDIP","metaDescription":"SN74F109N dual JK flip-flop from TI, 150 MHz clock, positive-edge triggered, complementary outputs, 4.5-5.5V supply, 16-PDIP.","metaKeywords":null},"attributes":{"series":"74F","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"JK Type","Series":"74F","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":"150 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-PDIP","Current - Quiescent (Iq)":"17 mA","Current - Output High, Low":"1mA, 20mA","Number of Bits per Element":"1","Max Propagation Delay @ V, Max CL":"8ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.91","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.91000","currency":"USD"},{"qty":10,"price":"$0.81400","currency":"USD"},{"qty":25,"price":"$0.77280","currency":"USD"},{"qty":100,"price":"$0.63490","currency":"USD"},{"qty":250,"price":"$0.59344","currency":"USD"},{"qty":500,"price":"$0.52444","currency":"USD"},{"qty":1000,"price":"$0.41404","currency":"USD"},{"qty":2500,"price":"$0.39060","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a83f252b53f21b7e7c8bb2afb92b54b2.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74F109N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74F109N when reusing this data.
