Instructions for Use:

1. Power Supply: Ensure the supply voltage (Vcc) is within the specified range of 4.75V to 5.25V.
2. Output Levels:
   • For a valid high output, VOH should be at least 2.4V when sourcing up to 0.4mA.
   • For a valid low output, VOL should not exceed 0.5V when sinking up to 16mA.
3. Input Levels:
   • A valid logic high input (VIH) should be at least 2V.
   • A valid logic low input (VIL) should not exceed 0.8V.
4. Propagation Delay: The typical propagation delay time (tpd) is 18 nanoseconds under standard conditions (Vcc = 5V, ambient temperature = 25°C).
5. Power Dissipation: Do not exceed 100mW power dissipation per package to avoid overheating.
6. Handling: Follow standard precautions for handling static-sensitive devices.

This table and these instructions provide essential information for the proper use of the SN74LS321N integrated circuit.
