Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 4.5V to 5.5V to avoid damage to the device.

2. Output Voltage Levels:

   • V_OH should be at least 2.4V and can go up to 3.6V when the output is high.
   • V_OL should be no more than 0.5V when the output is low.

3. Input Voltage Levels:

   • V_IH must be at least 2.0V to ensure a high input level.
   • V_IL must be no more than 0.8V to ensure a low input level.

4. Propagation Delay Time (t_pd):

   • The typical propagation delay time is 6ns, with a maximum of 11ns. This is crucial for timing considerations in your circuit.

5. Power Dissipation (P_D):

   • The maximum power dissipation is 100mW. Ensure that the device is not subjected to excessive power to prevent overheating and potential damage.

6. Operating Temperature (T_A):

   • The device can operate within the temperature range of -40°C to 85°C. Ensure that the ambient temperature stays within this range to maintain reliable operation.

7. Storage Temperature (T_STG):

   • When storing the device, ensure that the temperature remains between -65°C and 150°C to prevent damage due to extreme temperatures.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow proper soldering techniques to ensure good electrical connections without causing thermal stress to the device.

9. Mounting and Layout:

   • Ensure proper PCB layout to minimize noise and interference. Keep signal traces short and use decoupling capacitors near the power pins to stabilize the supply voltage.

By adhering to these parameters and instructions, you can ensure the reliable and efficient operation of the 74F258APC device.
