Instructions for Use:

1. Power Supply:

   • Connect the V_CC pin to a 5V power supply.
   • Connect the GND pin to ground.

2. Input Signals:

   • Ensure that input signals (A0, A1, A2, A3, B0, B1, B2, B3, S0, S1, S2, S3, G) are within the specified voltage range (0V to 5V).
   • Use pull-up or pull-down resistors if necessary to maintain stable logic levels.

3. Output Signals:

   • The output (Y) will be active low when the enable (G) is low and the select lines (S0, S1, S2) are set to select one of the inputs.
   • Ensure that the load connected to the output does not exceed the maximum current ratings (I_OL = 16 mA, I_OH = -0.4 mA).

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically 22 ns at 25°C. This value can vary with temperature and supply voltage.

5. Operating Temperature:

   • The device is designed to operate within the commercial temperature range (0°C to 70°C).

6. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the device.

7. Mounting:

   • Ensure proper mounting to avoid mechanical stress on the pins.
   • Use a socket if frequent replacement is anticipated.

8. Testing:

   • Test the device under controlled conditions to ensure it meets the specified parameters before integrating it into a larger circuit.

By following these guidelines, you can ensure reliable operation of the SN74LS158N multiplexer/demultiplexer.
