It operates from a 4.5V to 5.5V supply and delivers a maximum propagation delay of 5.5 ns at 5V with a 50 pF load. Each of the four independent NOR gates can sink up to 20 mA or source 1 mA per output. The input logic thresholds are 0.8V low and 2V high, making it directly compatible with standard 5V TTL and CMOS logic levels. The part is housed in a 14-SOIC surface-mount package and rated for commercial temperature range of 0°C to 70°C. ## 5.5 ns propagation delay — timing margin for high-speed buses The 5.5 ns max propagation delay (at 5V, 50 pF) is the key performance spec. In a 5V system running at 50 MHz or faster, this delay keeps the gate's contribution to the critical path under one clock cycle, preserving setup and hold margins. For slower buses or legacy glue logic, the 74F family's speed is overkill but still works — just watch that the fast edge rates can cause ringing if the PCB trace is not impedance-controlled. ## 20 mA sink current — driving multiple loads Each output can sink 20 mA and source 1 mA. ## Commercial temperature range — indoor use only Rated for 0°C to 70°C, this part is intended for indoor, office, or consumer environments. Not suitable for automotive under-hood, industrial ovens, or outdoor telecom cabinets without additional thermal management. For extended temperature, look at the 74FCT or 74ACT families. ## Active lifecycle, ROHS3 compliant It is ROHS3 compliant, meeting the latest EU directive for lead-free and restricted substances.","metaTitle":"SN74F02D 74F NOR Gate, 4-Ch 2-Input, 5.5 ns, 14-SOIC","metaDescription":"TI SN74F02D 74F quad 2-input NOR gate, 4.5V-5.5V supply, 5.5 ns propagation delay, 14-SOIC, ROHS3, active production.","metaKeywords":null},"attributes":{"series":"74F","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"74F","Package":"Tube","Logic Type":"NOR Gate","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","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-SOIC","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":"$1.22","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.22000","currency":"USD"},{"qty":10,"price":"$1.09400","currency":"USD"},{"qty":25,"price":"$1.03880","currency":"USD"},{"qty":100,"price":"$0.85330","currency":"USD"},{"qty":250,"price":"$0.79764","currency":"USD"},{"qty":500,"price":"$0.70490","currency":"USD"},{"qty":1000,"price":"$0.55650","currency":"USD"},{"qty":2500,"price":"$0.52500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4e6e1f6193b703a74f8dd3a54170390e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74F02D RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"Is SN74F02D compatible with 3.3V logic?","answer":"No, the SN74F02D requires a 4.5V to 5.5V supply.
