7408 / 74HC08 Quad 2-Input AND Gate IC

Overview

The 7408 / 74HC08 is a standard 74-series logic chip featuring four independent 2-input AND gates. An AND gate only outputs a “High” (1) signal when both of its inputs are “High.” This makes it an essential component for hardware-based decision-making, signal masking, and building basic computers from scratch.

While the classic 7408 (TTL) is great for older systems, the 74HC08 (CMOS) version is faster, consumes less power, and is 100% compatible with modern 3.3V and 5V microcontrollers like Arduino and ESP32.

Key Features

• Quad-Gate Design: Four independent AND gates in one chip—maximum efficiency for your breadboard.

• High-Speed Performance: The “HC” (High-speed CMOS) version offers rapid switching times with minimal power drain.

• Wide Voltage Range: Operates reliably from 2V to 6V, making it compatible with both 3.3V and 5V logic levels.

• DIP-14 Package: Industry-standard dual-in-line package fits perfectly into breadboards and IC sockets.
