Functional Features

• Serial-to-parallel data conversion: The IC can convert serial input data into parallel output data, allowing for efficient data processing.
• Shift register operation: It can shift the data bits through its internal registers with each clock pulse.
• Clear function: The clear input allows for resetting the shift register to its initial state.
• High-speed operation: The 74F164ASJX is designed to operate at high clock frequencies, enabling rapid data transfer.

Advantages and Disadvantages

Advantages

• Compact size and space-saving design.
• Wide supply voltage range allows for compatibility with various systems.
• High-speed operation facilitates fast data processing.
• Versatile application in digital electronics.

Disadvantages

• Limited number of parallel outputs (8 bits).

• Not suitable for applications requiring a large number of parallel outputs.

Working Principles

The 74F164ASJX operates based on the principle of sequential logic. When a clock pulse is applied to the CP pin, the serial input data (DS) is shifted through the internal registers, resulting in parallel output data appearing at the Q0-Q7 pins. The clear input (CLR) can be used to reset the shift register to its initial state.
