Instructions for Use:

1. Power Supply Connection: Connect the VCC pin to the positive supply and GND pin to the ground.
2. Enable Inputs: Ensure that the enable inputs are set correctly to activate the decoding function.
3. Input Configuration: Configure the binary input lines (A, B, C, D) according to the desired output line.
4. Output Usage: Only one output will be active at a time based on the binary input configuration. The active output will be LOW while all others remain HIGH.
5. Handling Unused Inputs: If not all inputs are used, tie unused input pins to logic LOW or HIGH as required by the circuit design to prevent floating states.
6. Decoding Table Reference: Refer to the decoding table in the datasheet to understand which binary input corresponds to which output line.
7. PCB Layout Considerations: Place decoupling capacitors close to the power supply pins to ensure stable operation.
