The 74LS08 is a Quadruple 8-bit Two Input AND IC, a digital circuit designed to process logic states. In an AND gate, two logic state signals are employed: HIGH (3-5 Volts) and LOW (0-2.6 Volts). Each AND gate has two input pins and one output pin, with the output transitioning to HIGH only when both input states are HIGH.

 

Features:

1. Low power consumption.
2. Fast operating speed.
3. Outputs in TTL, compatible with various devices and microcontrollers.
4. Independent use of a single AND gate without affecting others.
5. All four gates can be powered by a single power supply.

 

Specifications:

1. Operating voltage range: 4.75 – 5.25 Volts, recommended at 5 volts (up to a maximum of 7 volts).
2. 8mA maximum output current.
3. 18ns Rise and Fall time.
4. Temperature range: 0 to 70 degrees, with storage capability from -65 to 150 degrees.

 

Applications:

1. General-purpose logic operations using AND gates.
2. Widely used in Digital Electronics, Networking Devices, Servers, Memory Units, and ALU.
3. Versatile usage in various Digital Systems.
