Housed in a standard 16-pin Dual Inline Package (DIP), this monolithic integrated circuit contains a single logic gate equipped with an expansive 13 independent inputs. It is engineered to perform a massive Boolean NAND function: the output will go LOW (0) only if all 13 inputs are simultaneously HIGH (1). If even one input is LOW, the output remains HIGH.\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, the 74HC133 is widely utilized by hardware engineers and system designers to drastically reduce component count in complex address decoding circuits. Featuring a flexible operating voltage range of 2V to 6V, it interfaces flawlessly with both 3.3V microcontroller logic (such as ESP32 and STM32 boards) and standard 5V systems (like Arduino), making it an excellent choice for custom hardware prototyping and embedded memory expansion projects.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e 74hc133 ic, 13-input nand gate, 7400 series cmos, logic gate ic, dip-16 nand gate, address decoder ic.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLogic Family:\u003c\/strong\u003e 74HC (High-Speed CMOS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLogic Function:\u003c\/strong\u003e Single 13-Input NAND Gate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e 16-Pin DIP (Through-hole)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Supply Voltage (Vcc):\u003c\/strong\u003e 2.0V to 6.0V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Input Voltage (Min):\u003c\/strong\u003e 3.15V at 4.5V Vcc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Level Input Voltage (Max):\u003c\/strong\u003e 1.35V at 4.5V Vcc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -40°C to +85°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eDatasheet\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/M74HC133.PDF?v=1784894365\" target=\"_blank\" rel=\"noopener\"\u003eDownload 74HC133 Datasheet PDF\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMemory Address Decoding:\u003c\/strong\u003e Monitoring multiple address bus lines simultaneously to trigger chip-select (CS) pins on external RAM or EEPROM modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Glue Logic:\u003c\/strong\u003e Replacing cascaded networks of smaller 2-input or 4-input NAND gates with a single compact IC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePattern Recognition:\u003c\/strong\u003e Triggering a hardware interrupt only when a very specific, wide parallel binary sequence is detected.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecurity \u0026amp; Fault Detection:\u003c\/strong\u003e Consolidating multiple alarm or fault condition sensors into a single master alert output.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What happens if I don't need to use all 13 inputs?\u003c\/strong\u003e\u003cbr\u003eA: In any CMOS logic gate, you must never leave unused inputs floating. For a NAND gate, any unused inputs should be tied directly to Vcc (HIGH). Because the NAND gate requires all inputs to be HIGH to switch the output LOW, tying the unused pins HIGH essentially makes the gate ignore them, allowing it to evaluate only the inputs you are actively using.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need logic level converters to use this with an ESP32?\u003c\/strong\u003e\u003cbr\u003eA: No, as long as you power the 74HC133 using the same 3.3V rail that powers the ESP32. The 74HC family operates comfortably anywhere between 2V and 6V, so powering it with 3.3V ensures its logic thresholds match your 3.3V microcontroller perfectly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the 74HC133 a drop-in replacement for the 74LS133?\u003c\/strong\u003e\u003cbr\u003eA: Pin-for-pin, yes, they have the exact same footprint and pinout. However, the 74HC series is CMOS, which draws significantly less power and has different logic thresholds compared to the older TTL (Transistor-Transistor Logic) 74LS series. If replacing a chip in an older 5V system, ensure the driving components can properly sink\/source the CMOS logic levels.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 74HC133 13-Input NAND Gate IC – DIP-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ST Microelectronics","offers":[{"title":"Default Title","offer_id":48382922653934,"sku":"INC-01052","price":29.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/IC74HC133.jpg?v=1784895511","url":"https:\/\/www.tomsonelectronics.com\/products\/74hc133-13-input-nand-gate-ic-dip-16","provider":"Tomson Electronics ","version":"1.0","type":"link"}
