SN74HC32N-TEXAS INSTRUMENTS-Logic IC, OR Gate, Quad, 2 Inputs, 14 Pins, DIP, 74HC32

Description

The SN74HC32N, manufactured by industry leader Texas Instruments, is a high-speed CMOS logic IC containing four independent 2-input OR gates. As a fundamental building block of digital electronics, this chip performs the Boolean logical OR function—meaning the output will be HIGH (1) if at least one of its two inputs is HIGH (1).

Packaged in a standard 14-pin DIP (Dual In-line Package), this IC is incredibly easy to handle, making it a staple component for solderless breadboards, educational lab kits, and custom PCB prototypes.

Key Features:

• Genuine Texas Instruments Quality: Ensures highly reliable, consistent performance for academic and commercial applications.

• High-Speed CMOS Technology: Offers the perfect combination of fast switching speeds and very low power consumption.

• Breadboard Friendly: The standard 0.1-inch (2.54mm) pin spacing allows it to snap effortlessly into any standard breadboard or DIP socket.

• Wide Operating Voltage: Works seamlessly across a 2V to 6V range, making it highly compatible with 3.3V and 5V microcontrollers like Arduino and ESP32.
