Functional Features

• Converts serial input data into parallel output
• High-speed operation
• CMOS logic ensures low power consumption
• Can be cascaded to create longer shift registers
• Master reset function for clearing the register

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick data transfer - CMOS logic ensures low power consumption - Compact DIP package for easy integration into circuits - Cascadable for creating longer shift registers - Master reset function provides flexibility in data handling

Disadvantages: - Limited number of bits (8) may not be sufficient for certain applications - Requires external clock signal for proper operation - Not suitable for high-voltage applications

Working Principles

The MM74HCT164N operates based on the principle of serial-in/parallel-out shifting. It takes in serial input data through the SER pin and shifts it through the internal shift register with each clock pulse. The shifted data is then available at the parallel output pins (QH' and QH). The master reset (MR) pin can be used to clear the register and start fresh.

Detailed Application Field Plans

The MM74HCT164N finds applications in various digital systems where data storage and transfer are required. Some common application fields include:

1. Data communication systems
2. Serial-to-parallel data conversion
3. LED matrix displays
4. Control and interface circuits
5. Industrial automation systems
