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.
