Clock frequency is rated at 160 MHz, with a maximum propagation delay of 4.5 ns at 5 V into a 50 pF load. Output drive capability is ±32 mA, enough to feed a standard CMOS input or drive a small LED without an external buffer. Quiescent current is 10 µA, keeping the standing power low in battery-powered equipment. The SC-70-5 package (2.0 mm × 2.1 mm body) fits into dense PCB layouts where board area is at a premium. ## Supply voltage range and mixed-voltage interface One flip-flop variant can serve as a level translator between a 1.8 V microcontroller GPIO and a 3.3 V sensor, or between a 3.3 V FPGA and a 5 V legacy backplane. The input thresholds track VCC, so at 1.8 V the VIH is about 1.26 V; at 5 V it is 3.5 V. Input capacitance is 4 pF, which keeps the loading light on the driving node even when multiple flip-flops are paralleled on a shared clock line. The positive-edge trigger simplifies timing analysis because the setup and hold windows are referenced to the rising edge only. ## Propagation delay and timing closure The 4.5 ns max propagation delay at 5 V is the number to budget for worst-case timing. If the clock-to-Q delay of the driving flip-flop is 3 ns and the SN74LVC1G79DCKT adds 4.5 ns, the receiving register must have a setup time greater than 7.5 ns to avoid a metastability window. At 160 MHz the clock period is 6.25 ns, so this part is best used in one- or two-gate delay paths rather than deep pipelines at full frequency. For lower-speed clocks the margin is generous. ## Package and footprint for dense layouts The SC-70-5 package (also known as SOT-353) has a 2.0 mm × 2.1 mm footprint with 0.65 mm pin pitch. It is one of the smallest packages for a single-gate logic function. The five pins are VCC, GND, D, CLK, and Q. The small body means the decoupling capacitor must be placed close — a 0.1 µF ceramic in 0402 or 0201 size fits directly adjacent. No thermal pad is needed; the package dissipates through the leads and the small epoxy body. ROHS3 compliance is confirmed.","metaTitle":"SN74LVC1G79DCKT D-Type Flip-Flop, 160 MHz, SC-70-5","metaDescription":"Texas Instruments SN74LVC1G79DCKT single D-type flip-flop, positive-edge triggered, non-inverted output.","metaKeywords":null},"attributes":{"series":"74LVC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"D-Type","Series":"74LVC","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Standard","Output Type":"Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","Clock Frequency":"160 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.65V ~ 5.5V","Input Capacitance":"4 pF","Number of Elements":"1","Base Product Number":"74LVC1G79","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SC-70-5","Current - Quiescent (Iq)":"10 µA","Current - Output High, Low":"32mA, 32mA","Number of Bits per Element":"1","Max Propagation Delay @ V, Max CL":"4.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9400","priceTiers":[{"qty":1,"price":"$0.94000","currency":"USD"},{"qty":10,"price":"$0.84400","currency":"USD"},{"qty":25,"price":"$0.80120","currency":"USD"},{"qty":100,"price":"$0.65830","currency":"USD"},{"qty":250,"price":"$0.61532","currency":"USD"},{"qty":500,"price":"$0.54378","currency":"USD"},{"qty":1250,"price":"$0.42930","currency":"USD"},{"qty":2500,"price":"$0.40500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa2a278407e821e7297ee4b32123a463.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74LVC1G79DCKT/alternatives.json"},"ai":{"faq":[{"question":"Is SN74LVC1G79DCKT a direct replacement for SN74LVC1G79DBVT?","answer":"Both parts share the same base number 74LVC1G79 and identical electrical specifications.
