Instructions for Use

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (3.0 to 18V).
   • Connect the GND pin to the ground.

2. Enable Inputs:

   • The device has two enable inputs, ( overline ) and ( overline ). Both must be low (0V) for the decoder to operate.
   • If either enable input is high, all outputs will be high (1).

3. Address Inputs:

   • The address inputs (A0, A1, A2, A3) determine which of the 16 outputs will be active.
   • The output corresponding to the binary value of the address inputs will be low (0V), while all other outputs will be high (1V).

4. Output States:

   • Only one output will be low at any given time, corresponding to the binary address on the inputs.
   • All other outputs will be high.

5. Handling:

   • Handle the device with care to avoid static damage.
   • Ensure that the device is not subjected to voltages outside the specified operating range.

6. Testing:

   • To test the device, apply different combinations of binary values to the address inputs and verify that the corresponding output goes low.
