The SN74HC164D is a popular integrated circuit (IC) component that belongs to the 74HC series of high-speed CMOS logic devices. It is a 8-bit serial-in/parallel-out shift register that efficiently converts serial data input into parallel data output with the help of internal clock and control signals.
Key features of the SN74HC164D include:
1. Serial Input: The IC has a single data input (DS) which accepts serial data bit by bit. The data is internally shifted to the right with each clock cycle.
2. Synchronous Operation: The shift register performs the parallel data output (Q0-Q7) operation synchronously with respect to the clock signal (CP). This allows for accurate data transfer and synchronization with other ICs.
3. Serial Output: The IC offers a serial data output (Q7S) that can be connected to the serial input of multiple cascaded shift registers, enabling the expansion of the number of output bits.
4. Clock Input: The external clock input (CP) enables the control of data shifting within the register. It can be driven by various clock sources for flexibility.
5. Serial to Parallel Conversion: The main function of the IC is to convert the serial input data into parallel output data, where each bit occupies a separate output pin. This is useful in applications requiring parallel data transmission or storage
