It contains four independent NOR gates, each with two inputs, operating from a 4.5V to 5.5V supply. The 74F series is a high-speed bipolar logic family, and this part delivers a maximum propagation delay of 5.5 ns at 5V with a 50 pF load — fast enough for bus arbitration, address decoding, or control logic in systems where CMOS equivalents would add unnecessary gate delay. The commercial temperature range (0°C to 70°C) suits it for indoor equipment, office automation, and benchtop instrumentation where ambient temperature stays controlled. ## 5.5 ns propagation delay — what it means for the bus The 5.5 ns propagation delay (measured at 5V supply, 50 pF load) is the headline spec for this gate. In a 5V TTL system, that delay is tight enough to pass through several gate stages within a single clock cycle at 50 MHz without accumulating setup-time violations. The 74F family uses a bipolar process that gives faster edge rates than 74HC or 74LS, but also draws more supply current — a trade-off worth noting if the board is power-constrained. The output drive capability is 1 mA sourcing and 20 mA sinking, which is typical for this logic family and sufficient to drive one or two standard TTL loads per output. ## Active production — no LTB risk for this BOM line The SN74F02N carries an Active lifecycle status, meaning Texas Instruments continues to manufacture it without a last-time-buy notice. The part is ROHS3 compliant.","metaTitle":"SN74F02N 74F Quad 2-Input NOR Gate, 5.5 ns Propagation Delay","metaDescription":"SN74F02N 74F quad 2-input NOR gate in 14-DIP. 4.5V–5.5V supply, 5.5 ns propagation delay at 5V/50pF.","metaKeywords":null},"attributes":{"series":"74F","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74F","Package":"Tube","Logic Type":"NOR Gate","Mounting Type":"Through Hole","Package / Case":"14-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Number of Inputs":"2","Voltage - Supply":"4.5V ~ 5.5V","Number of Circuits":"4","Operating Temperature":"0°C ~ 70°C","Input Logic Level - Low":"0.8V","Supplier Device Package":"14-PDIP","Input Logic Level - High":"2V","Current - Output High, Low":"1mA, 20mA","Max Propagation Delay @ V, Max CL":"5.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.69","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.69000","currency":"USD"},{"qty":10,"price":"$0.60500","currency":"USD"},{"qty":25,"price":"$0.56840","currency":"USD"},{"qty":100,"price":"$0.46400","currency":"USD"},{"qty":250,"price":"$0.43096","currency":"USD"},{"qty":500,"price":"$0.36676","currency":"USD"},{"qty":1000,"price":"$0.29341","currency":"USD"},{"qty":2500,"price":"$0.26590","currency":"USD"},{"qty":5000,"price":"$0.25950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4e6e1f6193b703a74f8dd3a54170390e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the propagation delay of SN74F02N?","answer":"The maximum propagation delay is 5.5 ns at a 5V supply with a 50 pF load.
