74LS08 Pinout and Circuit Diagram - Logic AND Chip

Share
/ 2019-01-10 / Tech

74LS08 is a kind of logic gate ICs, including four independent gates each of which performs the logic AND function. It is used in systems where high speed AND operation is needed. as mentioned earlier the gates in the chip are designed by schottky transistors to make the switching delays of gates less. It features maximum supply voltage 7v, maximum current allowed to draw through each gate output 8mA.

Next it is mainly to introduce the 74LS08 pinout and 74LS08 circuit diagram for your demands.


74LS08 pinout

74LS08 has 14 pins, in total four groups of AND gates, knowing each pins individual usage to make the whole chip achieve its function.

The 74LS08 pinout can be found in the picture below:

74LS08 PINOUT

also the pin configurations for 74LS08 are labeled already.


74LS08 circuit schematic

A circuit schematic can better help us to understand circuits and components used, and it's a reference to make the actual circuit work.

Below is a fully labeled 74LS08 schematic diagram for reference.

74LS08 CIRCUIT

Main Features:

Referring to 74LS08 Features, the first scene we can think is that it works as logic AND IC.

Except that one, there still have some other features and applications we may need to know, which can help us to make use of it well, such as it is basically used where AND logic operation is needed, and we can use one or all gates simultaneously.
