Instructions for SN74ALS251NE4:

1. Power Supply: Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V.
2. Input Handling: Do not exceed the input voltage limits (-0.5V to VCC + 0.5V). Exceeding these limits can damage the device.
3. Output Levels: The high-level output voltage (VOH) should be no less than VCC - 0.5V when sourcing current up to -4mA. The low-level output voltage (VOL) should be no more than 0.5V when sinking current up to 8mA.
4. Propagation Delay: Expect a typical propagation delay of 16ns to 34ns at a supply voltage of 5V.
5. Power Management: Keep the power dissipation below 100mW to avoid overheating and potential damage.
6. Temperature Considerations: Operate within the temperature range of -55°C to 125°C for reliable performance. Store in an environment between -65°C and 150°C.
7. Handling Precautions: Use proper anti-static precautions to prevent damage from ESD (Electrostatic Discharge).
