Symmetric 8 mA output drive (both high and low) means it can directly drive downstream logic inputs or small loads without additional buffering, provided the total capacitive load stays within the datasheet derating curve. ## Active lifecycle with ROHS3 compliance The 2 µA maximum quiescent current keeps the power budget low in battery-powered or always-on subsystems. When the gate inputs are held at valid logic levels, the standby draw is negligible, which matters for systems that spend most of their time in a low-power idle state. ## Standard SOIC footprint for PCB integration No exposed thermal pad or special PCB land pattern is required — standard SOIC-14 footprint with a 0.050\" (1.27 mm) pitch will match. The surface-mount assembly is compatible with reflow soldering profiles typical for lead-free boards.","metaTitle":"SN74AHC02DR Texas Instruments NOR Gate, 4-Ch 2-Input","metaDescription":"Texas Instruments SN74AHC02DR quad 2-input NOR gate in 14-SOIC, 2V-5.5V supply, 8.5ns propagation delay at 5V, 8mA output drive, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"74AHC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Series":"74AHC","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"2V ~ 5.5V","Number of Circuits":"4","Operating Temperature":"-40°C ~ 125°C","Input Logic Level - Low":"0.5V ~ 1.65V","Supplier Device Package":"14-SOIC","Input Logic Level - High":"1.5V ~ 3.85V","Current - Quiescent (Max)":"2 µA","Current - Output High, Low":"8mA, 8mA","Max Propagation Delay @ V, Max CL":"8.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4","priceTiers":[{"qty":1,"price":"$0.40000","currency":"USD"},{"qty":10,"price":"$0.32400","currency":"USD"},{"qty":25,"price":"$0.29640","currency":"USD"},{"qty":100,"price":"$0.22050","currency":"USD"},{"qty":250,"price":"$0.19980","currency":"USD"},{"qty":500,"price":"$0.16536","currency":"USD"},{"qty":1000,"price":"$0.12402","currency":"USD"},{"qty":2500,"price":"$0.11368","currency":"USD"},{"qty":5000,"price":"$0.10680","currency":"USD"},{"qty":12500,"price":"$0.09990","currency":"USD"},{"qty":25000,"price":"$0.09750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/adff1a21821c2a853f2165297ec5a85b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74AHC02DR/alternatives.json"},"ai":{"faq":[{"question":"How can I order SN74AHC02DR or check availability?","answer":"The SN74AHC02DR is an active-production Texas Instruments part, available through independent distribution."},{"question":"Will SN74AHC02DR drop into a panel that was specified around SN74AHC1G00DBVT without rewiring?","answer":"No — the SN74AHC1G00DBVT is a single 2-input NAND gate in a different package (SOT-23-5 or SC-70-5), while the SN74AHC02DR is a quad 2-input NOR gate in a 14-SOIC.
