Each of the three gates accepts three inputs and delivers a standard NOR output, but the key feature here is the Schmitt-trigger action on every input — it cleans up slow, noisy, or non-monotonic edges before the gate switches. That makes this part a natural fit for industrial control boards, motor-drive interface logic, or any 3.3V or 5V backplane where signal integrity is marginal and a plain gate would oscillate or double-clock. ## Lifecycle and sourcing TI lists this part as Active with ROHS3 compliance. No NRND flag, no last-time-buy notice. It is a current-production standard-logic device, so new designs can commit to it without an obsolescence watch.","metaTitle":"SN74HCS27PWR NOR Gate, Triple 3-Input, Schmitt Trigger","metaDescription":"TI SN74HCS27PWR triple 3-input NOR gate with Schmitt trigger inputs, 2V–6V supply, 12ns delay at 6V, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"74HCS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74HCS","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Schmitt Trigger Input","Logic Type":"NOR Gate","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"3","Voltage - Supply":"2V ~ 6V","Number of Circuits":"3","Operating Temperature":"-40°C ~ 125°C (TA)","Input Logic Level - Low":"1V ~ 3V","Supplier Device Package":"14-TSSOP","Input Logic Level - High":"1.5V ~ 4.2V","Current - Quiescent (Max)":"2 µA","Current - Output High, Low":"7.8mA, 7.8mA","Max Propagation Delay @ V, Max CL":"12ns @ 6V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.37000","currency":"USD"},{"qty":10,"price":"$0.29900","currency":"USD"},{"qty":25,"price":"$0.27360","currency":"USD"},{"qty":100,"price":"$0.20350","currency":"USD"},{"qty":250,"price":"$0.18444","currency":"USD"},{"qty":500,"price":"$0.15264","currency":"USD"},{"qty":1000,"price":"$0.11448","currency":"USD"},{"qty":2000,"price":"$0.10494","currency":"USD"},{"qty":6000,"price":"$0.09858","currency":"USD"},{"qty":10000,"price":"$0.09222","currency":"USD"},{"qty":50000,"price":"$0.09000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a9039ba621115e50a14fafd2fdc5377f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does SN74HCS27PWR have Schmitt trigger inputs?","answer":"Yes, all three inputs on each of the three NOR gates include Schmitt-trigger hysteresis, making the part tolerant of slow or noisy edges."},{"question":"Can SN74HCS27PWR be used as a replacement for 74HCS27?","answer":"The SN74HCS27PWR is the Tape & Reel variant of the 74HCS27 triple 3-input NOR gate in a 14-TSSOP package.
