Instructions for Use:

1. Power Supply:

   • Connect the VCC pin to a supply voltage between 2.0V and 6.0V.
   • Connect the GND pin to ground.

2. Parallel Data Input:

   • Connect data inputs (D0-D7) to your parallel data source.
   • Ensure input voltages are within specified levels for logic high and low.

3. Control Signals:

   • PL (Parallel Load): Active low signal to load parallel data into the shift register.
   • SH/LD (Shift/Load): Controls whether the device is in shift or load mode.
   • CLK (Clock): Synchronizes the shifting of data out of the register.
   • CLK INH (Clock Inhibit): Disables the clock input when active low.

4. Serial Data Output:

   • Q7: Serial output that shifts data out on each clock pulse.
   • Connect this pin to the next device or microcontroller input as needed.

5. Operation Modes:

   • To load parallel data, set PL low and SH/LD high. Set PL high again to hold the data.
   • To shift data serially, set SH/LD low and apply clock pulses to CLK while keeping CLK INH high.

6. Handling:

   • This device is sensitive to electrostatic discharge (ESD); handle with care using proper ESD precautions.

7. Temperature Considerations:

   • Ensure the operating temperature remains within -40掳C to 85掳C for reliable operation.

8. Power Dissipation:

   • Keep power dissipation below 100mW to avoid overheating.

9. Propagation Delay:

   • At VCC=5V and TA=25掳C, expect a typical propagation delay of 35ns.
