8-Bit Parallel-Out Serial Shift Registers

Instructions for Using SN74HC164

1. Power Supply:

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

2. Data Input:

   • Connect the serial data input (DS) to the source of your serial data.
   • Connect the shift register clock (SH_CP) to the clock signal that shifts the data through the register.
   • Connect the storage register clock (ST_CP) to the clock signal that transfers data from the shift register to the output register.

3. Output:

   • The outputs (Q0 to Q7) will provide the parallel data after the storage register clock pulse.

4. Reset:

   • The clear input (CLR) can be used to reset the shift register. When CLR is low, all outputs are set to low.

5. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for the data to propagate through the shift register and appear at the output. Ensure that your clock signals have appropriate timing to avoid data corruption.

6. Power Dissipation:

   • Ensure that the power dissipation does not exceed 100 mW to prevent overheating and potential damage to the device.

7. Operating Temperature:

   • The device is designed to operate within a temperature range of -40°C to 85°C. Ensure that the operating environment stays within this range.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components. Use proper ESD protection when handling the device.

9. Testing:

   • Before integrating the SN74HC164 into your circuit, test it on a breadboard or test board to ensure it functions correctly.

10. Layout:

    • Keep the layout compact to minimize noise and interference. Use decoupling capacitors (e.g., 0.1 μF) close to the V_CC and GND pins to filter out any noise on the power lines.
