Instructions for CD74HC164M

1. Power Supply Connections:

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

2. Input Handling:

   • Ensure input voltages are within specified limits (VIL and VIH) to avoid incorrect logic states.
   • Use appropriate pull-up or pull-down resistors if necessary to stabilize inputs.

3. Output Considerations:

   • Outputs can source or sink current up to the specified limits. Ensure load currents do not exceed these values to prevent damage.
   • When driving capacitive loads, consider adding series resistors to limit peak currents.

4. Propagation Delay:

   • Account for propagation delay in timing calculations, especially in high-speed applications.

5. Temperature Range:

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

6. Storage and Handling:

   • Store in a dry environment and handle with care to prevent electrostatic discharge (ESD) damage. Use proper ESD protection measures when handling the device.

7. Mounting and PCB Layout:

   • Follow recommended PCB layout guidelines to minimize noise and ensure optimal performance. Keep power and ground planes robust to provide stable power distribution.

8. Testing:

   • Verify all connections before applying power. Test under typical operating conditions to ensure correct functionality.
