7427 Triple 3-Input NOR Gate IC (DIP)

The 7427 Triple 3-Input NOR Gate IC (DIP) is a standard 74xx TTL logic device that integrates three independent 3-input NOR gates in one 14-pin package. A NOR gate outputs HIGH only when all inputs are LOW, making it a powerful universal gate for building any digital function. Ideal for digital logic design, control and decision circuits, and educational labs. The DIP-14 package is breadboard-friendly for quick prototyping.

Key Features

• Three independent 3-input NOR gates (triple NOR)
• TTL 74xx family; typical 5V operation (4.75–5.25V)
• Fast switching with reliable TTL thresholds
• Direct interfacing with standard TTL/CMOS (with proper levels)
• DIP-14 package; easy for breadboards and PCBs
• Universal gate—can implement any logic function

Applications

• Combinational logic and decision circuits
• Enable/disable control, gating, and decoding
• Timing/sequencing and simple state logic
• Microcontroller/FPGA interfacing and prototyping
• Educational kits and student digital labs
