Instructions for Use:
74HC273D:
- Power Supply: Connect Vcc to the positive supply voltage (2V to 6V) and GND to ground.
- Clock Input (CLK): Apply a clock signal to the CLK pin to trigger the flip-flops.
- Data Inputs (D0-D7): Connect the data inputs to the desired logic levels.
- Clear Input (CLR): Active low input to reset all flip-flops to 0. Connect to ground to disable clearing.
- Output Enable (OE): Active low input to enable or disable the outputs. Connect to ground to enable outputs.
- Outputs (Q0-Q7): The outputs will follow the state of the data inputs on the rising edge of the clock signal when OE is low.
74HC653:

- Clear Input (CLR): Active low input to reset all flip-flops to 0. Connect to ground to disable clearing.

- Outputs (Q0-Q7): The outputs will follow the state of the data inputs on the rising edge of the clock signal when OE is low.
Notes:
- Ensure that the supply voltage is within the specified range to avoid damage to the IC.
- Use appropriate decoupling capacitors (e.g., 0.1μF) close to the power pins to filter out noise.
- For high-speed applications, ensure that the propagation delay meets the timing requirements of your system.
