The SN74LS68N is a popular Integrated Circuit (IC) component that belongs to the TTL (Transistor-Transistor Logic) family. It is a quad 2-input XOR gate with open collector outputs. Here's an overview and some key features of the SN74LS68N:
1. Logic Function: The SN74LS68N consists of four independent XOR (Exclusive-OR) gates, where each gate has two inputs and one output. XOR gates produce an output that is HIGH (logic 1) only when the number of HIGH inputs is odd.
2. Package Type: This IC comes in a 14-pin dual in-line package (DIP). It is designed to be mounted on a circuit board and can be soldered into place.
3. Power Supply: The SN74LS68N operates on a power supply voltage ranging from 4.75V to 5.25V, making it compatible with standard TTL logic levels.
4. Inputs and Outputs: Each gate of the IC has two inputs (A and B) and one output (Y). The inputs can accept logic signals between 0V (GND) and Vcc (supply voltage). The outputs are open collector type, meaning they can only sink current but cannot source current. Therefore, a pull-up resistor is required to provide the output voltage when the output is not actively sinking current
