Instructions:
- Power Supply: Ensure the supply voltage is within the specified range (1.65V to 3.6V). Connect Vcc to the positive supply and GND to ground.
- Signal Levels: Input signals should comply with VIH and VIL specifications to ensure proper logic levels are recognized.
- Output Loads: Outputs can drive TTL/CMOS inputs directly. Ensure load capacitance does not exceed recommended values for stable operation.
- Clear Function: The CLEAR pin resets all flip-flops to a low state when asserted. Ensure this pin is tied to the appropriate level if not used.
- Clock Synchronization: Data on the D inputs is transferred to the Q outputs on the rising edge of the clock pulse.
- Handling Precautions: Handle with care to avoid damage from electrostatic discharge (ESD). Follow anti-static protocols during installation.
- Mounting: Ensure proper mounting orientation and alignment of the component on the PCB to prevent soldering issues or mechanical stress.
