Instructions for TC74HC165AP

1. Power Supply Connection:

   • Connect the VCC pin to a power supply within the operating voltage range (2.0V to 5.5V).
   • Ensure the GND pin is connected to the ground.

2. Signal Input Handling:

   • For valid low input signals, ensure the input voltage does not exceed 0.8V.
   • For valid high input signals, ensure the input voltage is at least 2.0V.

3. Output Signal Handling:

   • When driving loads from the output pins, ensure that the output low voltage does not exceed 0.1V when sourcing up to 4.0mA.
   • The output high voltage should be at least 4.7V when sinking up to 0.4mA.

4. Timing Considerations:

   • Be aware of the propagation delay time which is typically 29ns under standard conditions (VCC = 5V, TA = 25°C).

5. Power Consumption:

   • The device consumes approximately 20μA at VCC = 5V and a frequency of 1 MHz.

6. Handling and Storage:

   • Store in a dry environment and handle with care to avoid damage from electrostatic discharge (ESD).

7. Application Notes:

   • Refer to the manufacturer's datasheet for detailed application circuits and advanced usage scenarios.
