Jul 10, 2025 · The 74LS02 (also known as 7402) is a TTL integrated circuit that contains four independent two-input NOR (Negated-OR) logic gates. Le logo est celui du fabricant Texas Instruments La série des 7400 1, 2 est une famille de circuits intégrés dont la caractéristique est d'utiliser la technique TTL. The original through-hole devices in dual in-line packages (DIP/DIL) were the mainstay of the industry for many decades. Electrical Characteristics. com Dec 14, 2022 · The 7402 (variants 74LS02, 74HC02) is a 74-series logic IC with four independent 2-input NOR gates. The power supply required is +5V. Learn how to use this chip in practical circuits with our 7400 Series IC Guide. Jul 29, 2024 · This page refers to the popular 7400 series IC The 7400 series is a popular set of logic ICs that can be ordered from many vendors, and used in many applications. Due to the popularity of these parts, other manufacturers released pin-to-pin compatible logic devices and kept the 7400 sequence number as an aid to identification of There are three symbols for NOR gates: the American (ANSI or 'military') symbol and the IEC ('European' or 'rectangular') symbol, as well as the deprecated DIN symbol. Switching Characteristics at Vcc=5V,Ta=25°C. Er enthält 4 NOR-Gatter mit jeweils 2 Eingängen. The ANSI symbol for the NOR gate is a standard OR gate with an inversion bubble connected. Today, surface-mounted CMOS versions of the 7400 series are used in various applications in electronics and for glue logic in computers and industrial electronics.
