Each of the two flip-flops stores one bit and drives complementary outputs, sinking or sourcing 24 mA per output — enough to drive a downstream logic input or a low-power LED indicator without a buffer. ## Timing and drive — what the 7 ns delay means on the bench Input capacitance is 7 pF typical — a light load on the driving stage, but in a high-fanout clock tree the cumulative capacitance of multiple 74LCX74FT inputs still needs a clock buffer rated for the total load.","metaTitle":"Toshiba 74LCX74FT D-Type Flip-Flop, 150 MHz, 14-TSSOP","metaDescription":"Toshiba 74LCX74FT dual D-type flip-flop with set/reset, 150 MHz clock, 7ns propagation delay at 3.3V, 1.65-3.6V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"74LCX","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"D-Type","Series":"74LCX","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Set(Preset) and Reset","Output Type":"Complementary","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"150 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 3.6V","Input Capacitance":"7 pF","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"14-TSSOP","Current - Quiescent (Iq)":"10 µA","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"1","Max Propagation Delay @ V, Max CL":"7ns @ 3.3V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.45","stockQuantity":17,"priceTiers":[{"qty":1,"price":"$0.45000","currency":"USD"},{"qty":10,"price":"$0.33900","currency":"USD"},{"qty":25,"price":"$0.30560","currency":"USD"},{"qty":100,"price":"$0.21110","currency":"USD"},{"qty":250,"price":"$0.17776","currency":"USD"},{"qty":500,"price":"$0.14444","currency":"USD"},{"qty":1000,"price":"$0.11110","currency":"USD"},{"qty":2500,"price":"$0.09999","currency":"USD"},{"qty":5000,"price":"$0.09444","currency":"USD"},{"qty":12500,"price":"$0.08610","currency":"USD"},{"qty":25000,"price":"$0.08055","currency":"USD"},{"qty":62500,"price":"$0.07222","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a7e4d0f78d05cef950aeeb5ee255699c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source to the 74LCX74FT?","answer":"The 74LCX273FT(AJ) and 74LCX273FT are octal D-type flip-flops from the same 74LCX family, but they are not drop-in replacements — the 74LCX74FT is a dual flip-flop (2 bits) with set/reset and complementary outputs, while the 74LCX273 is an octal (8-bit) with a common reset and non-inverted outputs only.
