Pinout
Here are the key pin functions:
- Data Inputs (D0-D7): 8 inputs for data.
- Outputs (Q0-Q7): 8 outputs that reflect the state of the corresponding inputs.
- Clock (CLK): Controls when the data on the D inputs is sampled and transferred to the Q outputs.
- Clear (CLR): Asynchronously resets all outputs to low when activated.
- Preset (PRE): Asynchronously sets all outputs to high when activated.
- Enable (EN): Allows or disables the clock operation.
The device operates at a wide voltage range and is designed for low power consumption. It is commonly used in digital circuits for data storage and transfer applications.
