Instructions for 74HC240:

1. Power Supply:

   • Connect the VCC pin to a power supply within the range of 2.0V to 6.0V.
   • Ensure the GND pin is connected to the ground.

2. Input Signals:

   • Apply input signals to the respective input pins (1A to 8A and 1B to 8B).
   • Keep input voltages within the supply voltage range to avoid damage.

3. Output Configuration:

   • The outputs (1Y to 8Y) can drive loads with current up to the specified limits.
   • Check the output high-level and low-level voltages to ensure compatibility with downstream circuits.

4. Propagation Delay:

   • Account for a typical propagation delay of 9ns when designing timing-sensitive applications.

5. Power Dissipation:

   • Ensure the device does not exceed a power dissipation of 100mW to prevent overheating.

6. Handling Precautions:

   • Use appropriate ESD protection measures during handling and installation.
   • Avoid exceeding maximum ratings as specified in the datasheet.

7. Operating Temperature:

   • Ensure the ambient temperature (TA) remains within the operational range specified by the manufacturer.
