Each of the four independent gates drives a wired-AND bus or interfaces to higher-voltage logic without external level shifting. Open-collector outputs sink up to 8 mA per channel (low state) and float high, allowing multiple gates to share a common pull-up resistor for wired-AND configurations. ## Supply and timing envelope Propagation delay is 32 ns max at 5 V with a 15 pF load, suitable for bus-oriented logic running at moderate clock rates. Supplied in a 14-SOIC package (0.154\" body width, 3.90 mm) with a tube carrier. The surface-mount footprint is standard for SOIC-14 and mates with common pick-and-place and reflow profiles.","metaTitle":"SN74LS26D Texas Instruments 74LS Quad 2-Input NAND Gate","metaDescription":"SN74LS26D from Texas Instruments, 74LS series quad 2-input NAND gate with open-collector outputs, 4.75V-5.25V supply, 14-SOIC.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74LS","Package":"Tube","Features":"Open Collector","Logic Type":"NAND Gate","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"2","Voltage - Supply":"4.75V ~ 5.25V","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":"-, 8mA","Max Propagation Delay @ V, Max CL":"32ns @ 5V, 15pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.25000","currency":"USD"},{"qty":10,"price":"$1.11900","currency":"USD"},{"qty":25,"price":"$1.06240","currency":"USD"},{"qty":100,"price":"$0.87280","currency":"USD"},{"qty":250,"price":"$0.81588","currency":"USD"},{"qty":500,"price":"$0.72102","currency":"USD"},{"qty":1000,"price":"$0.56922","currency":"USD"},{"qty":2500,"price":"$0.53700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/57abcae85ae1a41c467a07971399c436.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74LS26D functionally equivalent to MM74HC86MTC?","answer":"No. The MM74HC86MTC is a quad 2-input XOR gate from the 74HC family, while the SN74LS26D is a quad 2-input NAND gate with open-collector outputs.
