Instructions for Use:

1. Supply Voltage: Ensure the supply voltage is within the specified range of 4.5V to 5.5V.
2. Power-Up Sequence: Apply VCC before any input signals.
3. Clear Function: Active-low clear function resets all flip-flops to the low state when active.
4. Clock Enable: Use the clock enable pin to control whether the clock signal can affect the flip-flops.
5. Clock Signal: Apply a clock signal that does not exceed the maximum frequency of 30 MHz.
6. Input Signals: Ensure input signals are within valid logic levels for VIH and VIL.
7. Output Load: Keep output loads within the current limits specified by VOH and VOL.
8. Temperature Considerations: Operate within the temperature range specified to avoid damage or unreliable operation.
9. Decoupling Capacitors: Place decoupling capacitors close to the power pins to reduce noise and improve stability.
