The 2 µA maximum quiescent current means this gate adds negligible standby draw, so it fits into battery-backed or always-on domains without a power budget hit. The 7.8 mA output drive is enough to drive a single standard CMOS load or a low-power LED, but you will need a buffer for heavier fan-out. The -55°C to 125°C operating range covers underhood automotive, downhole, and avionics – capable is not qualified, but the thermal headroom is there for designs that need to survive beyond commercial limits. ## Lifecycle and sourcing reality This part carries an Active product status with ROHS3 compliance.","metaTitle":"SN74HCS00BQAR 74HCS Quad 2-Input NAND Gate, 12 ns @ 6V","metaDescription":"TI SN74HCS00BQAR quad 2-input NAND gate with Schmitt-trigger inputs, 2V–6V supply, 12ns prop delay, -55°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":"NAND Gate","Mounting Type":"Surface Mount","Package / Case":"14-QFN Exposed Pad","lifecycle_stage":"eol_hot","Number of Inputs":"2","Voltage - Supply":"2V ~ 6V","Number of Circuits":"4","Operating Temperature":"-55°C ~ 125°C","Input Logic Level - Low":"1V ~ 3V","Supplier Device Package":"14-WQFN (3x2.5)","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":"$0.58","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.58000","currency":"USD"},{"qty":10,"price":"$0.49300","currency":"USD"},{"qty":25,"price":"$0.46000","currency":"USD"},{"qty":100,"price":"$0.36800","currency":"USD"},{"qty":250,"price":"$0.34176","currency":"USD"},{"qty":500,"price":"$0.28916","currency":"USD"},{"qty":1000,"price":"$0.22345","currency":"USD"},{"qty":3000,"price":"$0.20373","currency":"USD"},{"qty":6000,"price":"$0.19059","currency":"USD"},{"qty":15000,"price":"$0.18600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/98bbfe0aec7796f0ce7ffc6f05f92ef1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74HCS00BQAR compatible with 3.3V logic?","answer":"Yes. The 2V to 6V supply range covers both 3.3V and 5V systems directly, and the Schmitt-trigger inputs accept the logic levels from those rails without external level shifting. Input logic low is 1V to 3V; input logic high is 1.5V to 4.2V, so a 3.3V CMOS output drives it cleanly."},{"question":"What are the alternatives to SN74HCS00BQAR?","answer":"The SN74LV00APWR is a quad 2-input NAND gate in the 74LV family, but it lacks Schmitt-trigger inputs and operates only up to 85°C. If you need an inverter instead of a NAND, the SN74HCS04PWR or the automotive-qualified SN74HCS14QDRQ1 are in the same 74HCS series with Schmitt-trigger inputs and similar supply and temperature ratings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HCS00BQAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HCS00BQAR when reusing this data.
