It belongs to the 74ACT series from Texas Instruments, a logic family that combines the speed of advanced CMOS with TTL-compatible input thresholds. Each of the six channels accepts a single input and delivers a clean inverted output, with the Schmitt trigger providing hysteresis that rejects noise on slowly changing or noisy input signals. ## Output drive and timing at 5 V The outputs source and sink 24 mA each, enough to drive standard TTL loads, small relays, or LED indicators directly without a buffer stage. Quiescent current is 2 µA maximum, meaning the chip draws negligible current when the inputs are static — useful in battery-backed or power-sensitive designs where the logic sits idle most of the time. The input logic levels are specified as 0.5 V to 1.4 V for low and 1.2 V to 2.1 V for high, which are TTL-compatible thresholds — a 5 V TTL output drives this input directly without a level shifter. The part is ROHS3 compliant, so it meets the current EU restriction on hazardous substances without exemptions. The supplier device package is 14-SO, the standard small-outline footprint for this pin count.","metaTitle":"SN74ACT14NSR Texas Instruments 74ACT Hex Inverter","metaDescription":"SN74ACT14NSR Texas Instruments 74ACT hex Schmitt-trigger inverter. 24mA output drive, 11.5ns propagation delay, 4.5-5.5V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"74ACT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74ACT","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Schmitt Trigger","Logic Type":"Inverter","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"1","Voltage - Supply":"4.5V ~ 5.5V","Number of Circuits":"6","Operating Temperature":"-40°C ~ 85°C","Input Logic Level - Low":"0.5V ~ 1.4V","Supplier Device Package":"14-SO","Input Logic Level - High":"1.2V ~ 2.1V","Current - Quiescent (Max)":"2 µA","Current - Output High, Low":"24mA, 24mA","Max Propagation Delay @ V, Max CL":"11.5ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.66500","currency":"USD"},{"qty":25,"price":"$0.62440","currency":"USD"},{"qty":100,"price":"$0.50950","currency":"USD"},{"qty":250,"price":"$0.47328","currency":"USD"},{"qty":500,"price":"$0.40280","currency":"USD"},{"qty":1000,"price":"$0.32224","currency":"USD"},{"qty":2000,"price":"$0.29203","currency":"USD"},{"qty":6000,"price":"$0.28500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6aa91fada0279b8c4503bb87a8f15302.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to SN74ACT14NSR?","answer":"The SN74LVC2G132DCUR is a different device — it is a dual 2-input NAND gate with Schmitt-trigger inputs, not a hex inverter.
