Instructions for Use:

1. Power Supply Connection:

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

2. Input Signal Levels:

   • For a valid low input signal (VI(L)), ensure the voltage does not exceed 0.8V.
   • For a valid high input signal (VI(H)), the voltage should be at least 2.0V.

3. Output Signal Levels:

   • When driving loads, ensure the output current does not exceed the specified limits to maintain VO(L) and VO(H) within acceptable ranges.

4. Propagation Delay:

   • The propagation delay time (tpd) is critical for timing considerations in your circuit design. At VCC = 4.5V and ambient temperature (TA) = 25°C, the typical delay is 22ns.

5. Power Dissipation:

   • Ensure that the power dissipation does not exceed 100mW continuously to avoid overheating or damage to the device.

6. Handling Precautions:

   • Handle the MM74HC574N with care to prevent electrostatic discharge (ESD) damage.
   • Follow standard precautions for handling static-sensitive components.

7. Storage Conditions:

   • Store in a dry environment to prevent moisture damage.
   • Keep away from direct sunlight and extreme temperatures.
