The SN74HC21 is a dual 4-input positive AND gate IC from the 74HC series, designed with advanced silicon-gate CMOS technology for high-speed operation and low power consumption. Each gate performs the Boolean function Y = A·B·C·D in positive logic, making it ideal for applications requiring multi-input logic control. It is pin-compatible with low-power Schottky TTL (LSTTL) devices and can be directly interfaced with standard TTL systems.

Key Features:

• Dual 4-input positive AND gates
• CMOS technology for high speed and low power
• Wide supply voltage range: 2V to 6V
• Low power consumption: typically 20 µA
• TTL compatible inputs
• Balanced propagation delay and output transition times
• Low input current: 1 μA max
• Available in DIP, SOIC, and other standard packages
• Operating Temperature: –40°C to +85°C

Applications:

• Logic level processing in digital systems
• Control systems and automation circuits
• Signal conditioning and multiplexing
• Arduino and microcontroller-based projects
• Educational electronics and digital logic learning kits

Package Includes:

• 1 x IC 7421 4-input AND Gate (SN74HC21)
