74LS08 is a Quadruple 8-bit Two Input AND IC. Gate AND gate is a digital circuit used to convert the logic state to a specific logic. In AND gate two logics state signals are used. The first one is HIGH, which is also known as 3-5Volts and the second one is LOW which is represented by 0-2.6Volts. A single AND gate use two input pins and one output pin. The output will also be in the HIGH and LOW state, but it will only HIGH when both input states will be HIGH.
- The IC has low power consumption.
- IC 74LS08 has a much fast operating speed.
- Its output comes in TTL, which makes it operate able with most of the devices and microcontrollers.
- A single AND gate can be used without affecting the other ones.
- A single power supply can turn all four gates.
- The operating voltage range of IC is 4.75 – 5.25 Volts. The voltage recommended for IC should be 5 volts but IC can hold up to 7 volts maximum.
- The IC gives 8mA maximum current at its outputs.
- IC 74LS08 has 18ns Rise and Fall time.
- It can operate in the temperature range from 0 to 70 degrees but it also has the ability to store the temperature of -65 to 150 degrees.
- 74LS08 IC used to perform general-purpose logic of AND gates.
- It is also used in the following devices
- Digital Electronics
- Networking Devices
- Memory Units
- The IC has wide use in multiple Digital Systems.
