Description
74LS86 is a quadruple XOR gate digital ICitconsists of a combination of two NOT, two AND & one OR gate. The output state gets LOW only at the same inputs. The output of the IC comes in TTL which makes it compatible to use with other TTL based devices and microcontrollers. The IC has wide use in designing an adder at the logic level.
Specifications:
- The power supply voltage for IC is 4.75 to 5.25. The Power can max up to 7V.
- The output current for the HIGH state is -0.4mA and for the LOW state is 8.0mA
- IC can work up in a temperature range from 0 to 70 degrees.
- The input voltage range for the HIGH state is a minimum of 2.0 and 0.8 for the LOW state.
- The input clamp diode can protect up to 1.5V.
- The IC has Propagation delay time for the HIGH state is 22ns and for the LOW state is 17ns.
Applications:
- It is used to make the Adder.
- The IC has multiple uses in Networking.
- Servers also have multiple uses of the XOR gate.
- XOR gate is also used in sequence detection for binary data.
