The MC74HC164AD is a popular integrated circuit (IC) component that belongs to the HC (High-Speed CMOS) family. It is a 8-bit serial-in, parallel-out shift register that enables efficient data transfer and manipulation in various digital applications. Here are some key features of the MC74HC164AD:
1. Shift Register Functionality: The MC74HC164AD primarily acts as an 8-bit shift register, allowing serial input of data and parallel output. It can store and shift 8 bits of data in the desired sequential order using a clock signal.
2. Serial Data Input: The IC has a single serial data input (DS) pin that accepts 8-bit data. Each bit of data is transferred in a serial format, one after the other, according to the provided clock signal.
3. Parallel Data Outputs: The MC74HC164AD provides parallel output of the shifted data through eight individual output pins (Q0-Q7). These pins allow simultaneous access to the respective bits of the shifted data.
4. Cascadable Design: The IC is designed to enable cascading of multiple MC74HC164AD devices, allowing the expansion of the number of shift register stages. This feature enhances the overall capacity and flexibility of the system by connecting multiple ICs together.
5. Schmitt-Trigger Input: The serial data input (DS) is implemented with Schmitt-trigger circuitry
