The MC74F164N is an 8-bit serial-in, parallel-out shift register manufactured by Freescale Semiconductor (now NXP). This device is part of the 74F family, known for its high-speed operation. It accepts serial data and shifts it through the register on each clock pulse, making the 8 bits of data available in parallel.
Applications

Additional Details
The MC74F164N is typically available in a DIP (Dual In-Line Package). The data is shifted into the register on the rising edge of the clock pulse. The two serial data inputs (A and B) are ANDed together internally. The clear input asynchronously resets all flip-flops to zero. Understanding the timing requirements of the clock and data inputs is crucial for proper operation in shift register applications.
