It integrates six independent inverter channels, each with a single input, in a 14-SOIC surface-mount package. The Schmitt-trigger action provides clean switching on noisy or slowly changing input signals, making it a standard choice for debouncing switch contacts, squaring up oscillator waveforms, and conditioning sensor outputs in automotive ECUs, body-control modules, and industrial controllers operating from 2 V to 6 V supplies. ## 21 ns propagation delay — timing budget for the bus For automotive programs that run several years, this avoids the supply-chain disruption of an unplanned obsolescence event. The AEC-Q100 qualification adds the reliability screening (temperature cycling, HAST, early-life failure rate) that automotive tier-1s and industrial OEMs require for zero-defect programs. The active lifecycle means standard lead times apply through the factory channel, and the ROHS3 compliance avoids any restriction on EU-market shipments.","metaTitle":"SN74HC14QDRQ1 Automotive Schmitt Trigger Inverter","metaDescription":"TI SN74HC14QDRQ1 is an AEC-Q100 qualified hex Schmitt-trigger inverter in 14-SOIC. 2V–6V supply, 5.2mA output, 21ns prop delay at 6V.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, 74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Automotive, AEC-Q100, 74HC","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Schmitt Trigger","Logic Type":"Inverter","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"1","Voltage - Supply":"2V ~ 6V","Number of Circuits":"6","Operating Temperature":"-40°C ~ 125°C","Input Logic Level - Low":"0.3V ~ 1.2V","Supplier Device Package":"14-SOIC","Input Logic Level - High":"1.5V ~ 4.2V","Current - Quiescent (Max)":"2 µA","Current - Output High, Low":"5.2mA, 5.2mA","Max Propagation Delay @ V, Max CL":"21ns @ 6V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0","priceTiers":[{"qty":1,"price":"$1.00000","currency":"USD"},{"qty":10,"price":"$0.89400","currency":"USD"},{"qty":25,"price":"$0.84880","currency":"USD"},{"qty":100,"price":"$0.69730","currency":"USD"},{"qty":250,"price":"$0.65180","currency":"USD"},{"qty":500,"price":"$0.57600","currency":"USD"},{"qty":1000,"price":"$0.45474","currency":"USD"},{"qty":2500,"price":"$0.42900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/371c4bf0ee71bcdf5f20d6dcfdabdd96.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74HC14QDRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is SN74HC14QDRQ1 a direct replacement for 74HC14?","answer":"Yes, the SN74HC14QDRQ1 is functionally identical to a standard 74HC14 hex Schmitt-trigger inverter, but adds AEC-Q100 automotive qualification and the full -40°C to 125°C temperature range.
