Pinout
- Inputs (D0-D7): Data inputs for each latch bit.
- Clock (CLK): Triggers the latching of the data when it transitions from low to high.
- Output Enable (OE): Activates or deactivates the outputs; when low, outputs are enabled.
- Latch Enable (LE): When high, allows the data on the D inputs to be latched on the next clock pulse.
- Outputs (Q0-Q7): Buffered outputs for the latched data.
- Ground (GND): Common ground connection.
- Vcc: Power supply connection.
This device is commonly used in digital circuits for data storage and transfer applications.
