DIP IC 74ls08


SKU: 000367 Categories: , Tags: , ,


The 74LS08 is a widely used integrated circuit (IC) that belongs to the 74LS series of logic gates. Specifically, it is a Quad 2-Input AND Gate IC. This IC contains four separate AND gates, each of which has two input terminals and one output terminal. The 74LS08 is a staple in digital electronics due to its ability to perform logical operations, specifically AND (logical conjunction) operations.

Key Features:

Number of Gates: The 74LS08 IC integrates four individual AND gates in a single package, allowing multiple logic operations to be performed in a compact design.

2-Input AND Gates: Each AND gate has two input pins and one output pin. These AND gates perform logical operations on the two input signals.

Logic Function: AND gates perform the logical operation where the output is “high” (logical 1) only when both input A and input B are “high” (logical 1).

Compatibility: The 74LS08 IC is part of the TTL (Transistor-Transistor Logic) family, ensuring compatibility with other TTL logic devices.

Wide Voltage Range: Typically, this IC operates over a broad voltage range, making it compatible with various supply voltages, such as 5V.

DIP Package: The 74LS08 IC is commonly available in a Dual Inline Package (DIP), which simplifies its use in breadboards and on PCBs (Printed Circuit Boards).


Logic Operations: Used to perform AND logic operations in digital circuits, a fundamental element for constructing complex digital systems.

Signal Processing: Employed in signal processing, arithmetic, and control circuits within microcontrollers and microprocessors.

Combinational Logic: Integrated into combinational logic circuits, which are responsible for creating functions and performing data processing.

Multiplexing and Demultiplexing: Utilized in multiplexer and demultiplexer circuits to select and distribute data signals.

Memory Address Decoding: In microcontroller and microprocessor designs, AND gates are used for memory address decoding.

Data Routing: Used to route data and control signals in various digital systems.

The 74LS08 Quad 2-Input AND Gate is a fundamental building block in digital electronics. Its ability to perform AND logic operations makes it versatile for use in a wide range of digital circuits, from basic combinational logic to complex digital systems.
