The hysteresis cleans up slow or noisy edges — a 0.3V to 1.5V low-level threshold and 1.5V to 4.2V high-level threshold give roughly 1.2V of typical hysteresis at 4.5V supply, so a 50 mV/ns slew rate on the input still produces a clean output transition. Quiescent current maxes at 1 µA across temperature, so the part adds negligible standby draw in always-powered modules. Output drive is 5.2 mA source and sink at rated supply — enough to switch a downstream gate input or a low-current LED indicator, but not a relay coil. Propagation delay is 21 ns max at 6V into 50 pF, which sets the data-path timing budget for a 24 MHz SPI bus or a 1 MHz PWM loop. ## Automotive temperature range and qualification The package is MSL1 (moisture sensitivity level 1, per the ST datasheet for this family), so no bake-out is needed before reflow if the shelf life is under the floor-life limit. ## Active production, RoHS3 compliant The part is RoHS3 compliant (EU 2015/863), with no exemptions for lead in solder or decaBDE in the molding compound. The closest functional peer is the M74HC14YRM13TR — same die, same logic, same AEC-Q100 grade, same 14-TSSOP package. The difference is the reel option: YTTR ships in tape-and-reel only; YRM13TR adds a cut-tape and Digi-Reel option for prototyping. Both drop into the same PCB footprint and BOM position without a layout change.","metaTitle":"STMicroelectronics M74HC14YTTR Hex Inverter, Schmitt Trigger","metaDescription":"STMicroelectronics M74HC14YTTR hex inverter with Schmitt trigger inputs. 2V-6V supply, -40°C to 125°C, AEC-Q100 automotive grade. 14-TSSOP package.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, 74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"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-TSSOP (0.173\\\", 4.40mm 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 ~ 1.5V","Supplier Device Package":"14-TSSOP","Input Logic Level - High":"1.5V ~ 4.2V","Current - Quiescent (Max)":"1 µA","Current - Output High, Low":"5.2mA, 5.2mA","Max Propagation Delay @ V, Max CL":"21ns @ 6V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.02","priceTiers":[{"qty":1,"price":"$1.02000","currency":"USD"},{"qty":10,"price":"$0.91200","currency":"USD"},{"qty":25,"price":"$0.86560","currency":"USD"},{"qty":100,"price":"$0.71120","currency":"USD"},{"qty":250,"price":"$0.66480","currency":"USD"},{"qty":500,"price":"$0.58748","currency":"USD"},{"qty":1000,"price":"$0.51048","currency":"USD"},{"qty":2500,"price":"$0.51048","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/111ff7baa7579764d14780b438ee898c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M74HC14YTTR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for M74HC14YTTR?","answer":"The M74HC14YRM13TR is the closest functional equivalent — same 74HC14 die, same AEC-Q100 qualification, same 14-TSSOP package, same electrical specs.
