Functional Features

The MC74HC164AD is a high-speed CMOS logic integrated circuit that serves as an 8-bit serial-in/parallel-out shift register. It allows for the conversion of serial data into parallel data. The device operates within a wide supply voltage range of 2V to 6V and can handle clock frequencies up to 25 MHz.

Advantages and Disadvantages

Advantages: - High-speed operation - CMOS logic for low power consumption - Compact SOIC package for space-saving designs - Wide supply voltage range allows for flexibility in various applications

Disadvantages: - Limited number of outputs (8) - Propagation delay of 60 ns may not be suitable for extremely time-sensitive applications

Working Principles

The MC74HC164AD works by receiving serial data through the A pin and clock pulses through the B pin. The clock input synchronizes the shifting of data bits within the shift register. On each clock pulse, the serial data is shifted into the register, and the previously stored data is shifted to the next output. The parallel data outputs (QA-QH) provide the converted parallel data.

Detailed Application Field Plans

The MC74HC164AD can be used in various applications that require serial-to-parallel data conversion. Some potential application fields include:

1. LED Matrix Displays: The shift register can be used to control multiple LEDs in a matrix arrangement, allowing for efficient control and reduced pin count.
2. Data Communication Systems: It can be utilized in serial data transmission systems to convert incoming serial data streams into parallel data for further processing.
3. Industrial Automation: The shift register can be employed in industrial control systems to handle parallel data inputs from sensors or other devices.
