Instructions for Using 74HC125D

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (2.0V to 6.0V).
   • Connect the GND pin to the ground.

2. Input Signals:

   • Ensure that input signals are within the valid range: V_IL (0.8V to 1.5V) for low and V_IH (3.5V to 4.0V) for high.
   • Avoid applying voltages outside the supply range to prevent damage.

3. Output Signals:

   • The output will be low (V_OL) when the input is low and high (V_OH) when the input is high.
   • Ensure that the load connected to the output does not exceed the maximum current ratings.

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically 10 ns at V_CC = 4.5V. This value can vary depending on the supply voltage and temperature.

5. Temperature Considerations:

   • Operate the device within the specified temperature range (-40°C to 85°C) to ensure reliable performance.

6. Handling Precautions:

   • Handle the IC with care to avoid static discharge, which can damage the sensitive components.
   • Use proper anti-static measures such as wrist straps and grounded work surfaces.

7. Storage:

   • Store the IC in a dry, cool place to prevent moisture damage.
   • Keep the IC in its original packaging until ready to use to protect it from static and physical damage.
