SN74HC02N Pinout

The SN74HC02N is a quad 2-input NOR gate IC from Texas Instruments, featuring four independent NOR gates in a 14-pin DIP package. This high-speed CMOS logic chip is widely used in digital circuits for implementing logic functions. The pinout includes inputs and outputs for each gate, with power supply connections at pins 7 (GND) and 14 (Vcc). Each gate has two input pins (A and B) and one output pin (Y), clearly organized across the dual-inline layout for straightforward circuit integration.

The SN74HC02N’s standardized pinout makes it ideal for prototyping and educational applications where basic logic operations are required. Its compatibility with TTL and CMOS levels ensures wide usability across logic circuits, offering reliable NOR gate functionality in a compact DIP-14 package.
